Paint
 
hey guys, I am going to be painting my 69 chevy pickup soon and have a few questions. I will be painting it a flat black to make it more unique of a classic and I just love the flat look. My question is how the prime works. I constantly hear self etching primer, epoxy primer, and primer filler? what are these used for? Am I suppose to use all three of them or what? Im not going for absolute show quality on my truck, just a paintjob to make it look better. But if you could please help me with my primer question.

Thanks

etch and epoxy primers are for use on bare metal filler primer is just that a primer that can be used to level out the surface via block sanding most epoxy primers can also be used as a sealer.

primer
 
Short answer: You should always use some type of epoxy primer whenever you go down to bare metal, as epoxy primer goes along way toward the prevention of rust. Whenever you spray epoxy primer, you must use a charcoal type mask or better or you will be coughing for quite awhile.

Filler primer (aka primer-surfacer) is what you spray on and sand off while you are doing bodywork.

Longer answer: For the best results, you should strip (chemically or mechanically) all of the sheet metal down to bare metal, as you never know for sure what lies beneath. When everything is down to bare metal, spray epoxy primer according to the specific brand's directions. After the appropriate drying time, spray a couple coats of filler primer. Do whatever body work you need to do, prime with more filler primer, sand, and repeat until the body is as good as you want it. Then apply sealer, then paint.

primer
 
I'm sorry, I probably wasn't clear in my post about the epoxy primer. I usually spray epoxy primer on everything, whether it is bare metal, OEM finish, or whatever. The epoxy primer provides an excellent surface for body filler and other substrates to adhere to.

You should not use the epoxy primer alone as a topcoat however. If when the body work is as good as you want it, apply sealer, and then the paint of your choice. If you are looking for a suede or primer look as the finished paint, then use a single stage paint with some flattener added. Or you might explain to the counterman at the paint store what you are looking to do and he might have some less expensive paint that is designed for trailers, farm implements and such. I did this at a PPG dealer a few years ago and he saved me a bunch of money, but I don't recall what the stuff was called.

You definitely dont want "flat" black... satin or matte black maybe but not flat... it will look like crap in no time.
