Can anyone recomend a good quality 2k lacquer in a spray can, i know your meant to use the same brand as whatever base your using but im trying to find out if theres any out there which are better than others. Harder wearing is what im after mainly but also need a good shine to it

im still not sure on how this is a 2k lacquer...

HB Body Professional 2K Clear Car Lacquer 400ml Clearcoat Aerosol | eBay

you dont add the activator too it, apparently it reacts with the air and is 2k. I only know this as i asked the seller before i tried one, the stuff sets really hard but can it be as good as the ones you do add activator too?

thanks
 
I've used a 1k acrylic lacquer from UPol with a gun over water-based basecoat and it was fine and has handled the UV.

What you really need to test if you get any reactions by mixing and matching products, buy one as a tester can and give it a go. If it dries through evaporation and not through chemical reaction it can't be a true 2k but I think some of the smart product 1K products are now so good that for a small area they should nearly be as good.

Also notice that the one you link is Medium Solid and not High Solid, so many need extra coats to achieve the thickness needed for durability.
 
Personally I've only used lacquer from a can once and from memory you can achieve great results

The only thing to remember is lacquer in a can is thinned all the way down to get it to flow through a pressurised can. So be careful when you are spraying it, 3 lights coats and a slight heavier coat will be adequate. This is really easy to run, to keep about a 60-70cm spray distance I would say. Although does depend on the brand and nozzle type that's on the can

Medium solid doesn't suggests that it needs more coats. Medium solid means the paint/lacquer stays wetter for longer thus creating less dry spray areas if you we're using a high solid
 
cheers for the help

"If it dries through evaporation and not through chemical reaction it can't be a true 2k"

may be a dumb question but how can you tell between a chemical reaction and evaporation?

each coat ive put on takes about 15 min to dry, i left it a couple hours before wet sanding and re-coating and it handled the wet sand fine, came up really nice after using 3 different grades of sanding pad and some polish.

yeah ive noticed how thin spray can clear is, its taken me a while but i know how much to use just before it starts to run, putting on 2 medium coats instead of a few thin layers has given me better results

ive tried upol 1k and wasnt impressed, mainly because the can i bought didnt have enough pressure in so was left holding the nozzle about 2" from my project and thought fcuk this and never used it again

is there a brand of spray can 2k clear which is worth trying before buying another of the cans in that link

thanks
 
If it was evaporation then if you force air onto it you will physically see it drying out as you do with water based paints

But for all lacquers (as of the now) are all 1k and 2k products
It was just a guide line incase you haven't used an aerosol can before. Stuff is ridiculously thin, everyone has their own way to applying it

Lesonal is the only proper 2k lacquer I've used. It has a small catrige that releases 2k hardener within the can itself. Very very expensive. It's good but I can't compare it to any other brands

I don't see anything wrong with the one you have listed
 
Didn't know that about MS/HS, I always went for everything HS because I was told HS meant it would go on thicker by a paint supplier! Good info Silva :)

Anything from a can is very thin, I'm yet to use a high build primer from a can that is any good at all.

Remember the safety aspects of 2K as well, you don't want to be around it any more than necessary especially without an air-fed mask.
 
i know this brand, and particular product. I don`t know how much of a true 2K it is, but you need to bake or leave over night prior handling. Remember to shake the hell out of it before application. I don`t know if 496SR (scratch resistant) comes in a can, but it`s good stuff.

A lot of the time people will reccomend matching clears and bases to cover their arses, truth be told in the 15 years I was painting before snap on 99% of products with work with one another, with the boats I used to paint I always used ici base coats with a grip clear and not once had a problem. Hs came about to comply with environmental issues, more build with less coats so less over spray to ruin the atmosphere. Paints like ****, over thin or over apply and it pops real bad, ms is much more forgiving flows a lot better flat and polishes to a better finish and generally a nicer product to use.
 
good info, cheers for the replys

ive been using what i thought was a good mask, a dual cartridge mask but after hearing people say i need a air fed mask and doing more research im not touching the stuff until i get protected against the fumes. To be honest its been 4days since i sprayed anything and my lungs feel shot, i knew 2k was dangerous but didnt know how dangerous exactly, it feels like ive just smoked 20cigs one after the other. Lesson learnt i guess:(

scratch resistant lacquer sounds what id be after, its to go on plastic which will be handled alot so il look into that, and also that lesonal 2k.

has anyone got a idea of the price range you have to spend to protect yourself against 2k fumes, ive got a little compressor for my airbrush which could manage a constant 50psi but dont know if that enough?

what do you mean by this exactly? thanks!
 
That will be nowhere near enough air. You'd even be struggling on a 3HP to use a mask and a full size gun at constant use.

I bought fire fighter breathing apparatus and am in the process of finding someone to attach a line from it to scuba tanks as the BA tanks are too small and out of date (date is very important with this stuff). Much cheaper as the cost of the filters is in the hundreds and being able to actually put the compressor far enough away etc. is a major ball-ache.
 
@pateras_vtec... sorry i read it wrong before, i thought you were talking about doing something with the paint can before using it, yeah i usually leave it overnight before giving it a wetsand but have tried it after 4 hours and it was fine, i just sanded very lightly

@championshipwhite... thanks for the offer il get back to you on that, im still doing abit of research into the different kits available but that sabre mask looks good, how is the seal which goes around your face? visability good when using it?

i used to have a scuba tank aswel :angry2:
 
If you've been exposed to these chemicals in say your garage with the door down. How quickly are you likely to die?
 
sounds like you've had a lungfull too??

i cant say how long itd take you to die if constantly exposed but i can imagine you'd know about it before you do, dizzieness, headaches etc ?

The first night after doing alot of spraying i was freezing cold, ended up putting a coat on while sat downstairs and was getting colder, couldnt work it out so i went online and found out being exposed to 2k can give you flu like shivers! :nono: the next few days ive been constantly tired and could tell it had got on my lungs as my breathings been shyte. Its only this afternoon ive started feeling better and its been 4 or 5 days since i touched it.

this stuff should really come with a massive warning sticker

Well they are toxic chemicals.. No hard and fast rule really. It all depends on quantities and number of exposures...

If you overwhelm yourself with enough of it, you'll be dead in 5 mins.

If you have repeated exposure to low levels eventually you'll probably die of respiratory complications and or cancers caused by mutations of damaged cells

Thats new to me. I thought all cans were 1k down to the lack of hardener!
 
Been awhile since I sprayed 2k. But I'd say I've done been exposed to probably 4-5hours total. This is over the years obviously not in one sitting Just wondering what the complications of it.

Had enough of it to feel dizzy befor. I used to lift the garage do and sit outside for 5mins then crack on, also headaches.
 
It's the isocyanates which are the most dangerous part, they can cause paraylsis of the lungs and you become sensitised to it so a small does next time can cause the same damage as a larger dose.

The cost of a set-up is £300'ish for a suitable compressor, probably more, as the mask requires a constant amount of air the duty cycle has to be very good so even if it is 3hp etc. it has to flow the cfm constantly and many of the cheaper compressors have poor duty cycles. It then has to be filtered and the filtering system is roughly £150, and the mask itself is roughly £150. It then has to be placed away from any fumes.

For spot repairs you are fine priming with 2k using a roller or brush and a charcoal mask, but you have to make sure it doesn't touch bare skin as it will be absorbed.

The breathing apparatus is positive air pressure so it doesn't need to fit snugly as the air is pushing out from under it so nothing can get in. To be honest I think I've just talked myself out of selling it!
