Will the same premier on different materials give a lighter and darker typr of base? (fiberglass, galvanized steel, body filler, and steel) Is there one primer that will work on all? Should an etching primer be used on fiberglass fenders? <img src="confused.gif" border="0">

there are many different kinds of primers, read the labels or talk to a supply person, self etching is for steel, has a mild acid in it to etch the metal to ensure adhesion.

My brother used the exact same color of paint as me but he used gray primer and I used red oxide primer. The cars were two different colors. (that doesn't take into affect that we have two differnt styles of painting also) I've never seen a difference when using the same primer on different materials- aluminum, steel. fibo. BOBCRMAN is right on- etch for steel, not fibo (in my book!)

Dragon was right about the color difference because of the color of the primer. There will be a likely difference if you are painting on rubber parts like the new bumper covers and use a flex additive, however. Even the manufacturers can't get that right. Just walk through a new car lot and look at them.

Interesting experience with Dupont Chromabase. They recommend a Value Shade before shooting the base coat to ensure the same color, regardless of primer color. If you don't continue this Value Shade, it is impossible to match the color again!!

NAPA's (Martin Senor)5205 primer says works on steel, aluminum, fiberglass. Straight on no etch. I just put in on and it dries glossy make the block sand easy to see. Also says no sealer. Put on 2 coats then block sand then final coat to base. Only thing $200.00 a gallon.
