Hi everyone,
By any chance do we have any professional car painters/ panel beaters on site?
 
Quick on, when priming filler best use etch primer? And then a normal primer over or what do you reckon?
 
not sure about the translation of all the terms, but if etch primer is what I think it is, then is only needs to be applied at sections where the metal is exposed. It wouldn't be bad on the other places, but it's pretty useless. Etch primers comes before the normal primer.
 
Top painter in scotland ;)

Etch primer is only used on bare metal, prevents corrosion and adhesive properties

Hi build primer/primer filler is normally used to surfaces where it may be slightly uneven and requires a slight build to level the surface. This will then be required to sand and flatten back
 
Yep think thats more or less what i was thinking. Just want to make sure its right.

Obviously the more /finer u sand the better?
 
Well normally according to most MDS primer needs to be sanded with 500 or upto 600 grit (dry)in order to have a scratch free finish. This depends on which paint you're using
If its rattle cans I would go as high as 800 grit (dry)

Matt black its a 2k colour but without the laquar. Its avw colour lm something :)
 
2k always have a better coverage than your normal water based and even solvent base paints. But to be sure I would finish up to 600 grit dry paper. It's better being safe than sorry :)
 
Etch primer is old hat now according to some, the high end resto places now use epoxy primer as it can be applied to the bare metal and filled over so there is nothing which is porous in contact with the metal at any point. When used wet-on-wet it can be a barrier coat and allow better adhesion also.

Also, if you are using 2k paint make sure you are aware of the health implications.

thats the plan :) was thinking half a litre of thinners to a litre of paint , should do the trick.might get away with two coats.

the Isocyanates are the real danger arent they? i wonder how safe is safe with this stuf.. if you could and dust didnt exist youd nearly want to paint it outside.
 
Etch primer is still used widely in the bodyshop industry. It is by far quicker grabbing an aerosol can of etch primer then it is to set up an air gun and mixing paint and spraying it and then having to clean your gun etc etc
Epoxy primers are used also only ever seems to be used in old resto restoration each to their own I guess.
If the panel is prepped right then results are most of less the same
 
Yea areosol would be the vest bet too much hardship setting up a gun with two mins work.
