ITEMS YOU NEED:
-- sand blaster (you can use regular sheets of sand paper BUT it will take you FOREVER and you wont get in between all the cracks and crevises or use a paint stripper )
--1 can of primer, 1 can of paint (what ever color you choose doesnt HAVE to be high temp any brand/color/texture will work) 1 can of clear. NOTE you dont HAVE to use clear yes it does make it easire to clean off grease, dirt and what not. PLUS it makes it shine!
--1 piece of cardboard and 1 house hold oven.
thats all the items you need
1) prep the valve cover. Make sure to tape off the holes to ensure no sand from the sandblaster gets in the gaskets to the spark plugs. When you think you have sand blated it well, do it again just to make sure it is clean. It should look white if it is good and done.
use a air hose and spray the inside and outside out of the VC. If you have one available to, you can use a parts cleaner and clean it off.
2) after it has dried and you have wiped it off, use the primer and lay on a nice thin even coat. allow it to dry for a good half hour then apply up to 2 or 3 more depending on how well of a job you did on the sandblasting. Allow it to dry for 1-2 hours after all the coats have been applied.
3) Once it has dried apply a thin layer of a color of your choice on the valve cover. leave the spray head 5-7 inched from the VC to ensure a nice smooth, even coat of paint. After allowing it to dry, apply another coat doing the same process. Leave the coat of paint dry for 2-4 hours.
4) after it has dried apply a thin layer of clear coat. allow it to dry. once it has dried pre heat the oven to 325 degrees. place the VC on the top highest rack in the oven. Keep it in there for 10-15 minutes. This lets you know a good seal was made with the clear.
turn off oven and let it cool for awhile take it out and admire
just some side notes the better quality paint you buy, the better the work will show in the finished product.
now have some fun
