I have been working on my 65 for 2 1/2 years now. Doing it as time allows. The trunk has been replaced, quarter skins, deck lid, etc with all GoodMark parts and most all the pant has been sanded down to bare metal or close to it. The Ecoat is still on the replacement panels. During this time I have used some rattle can primer to cover bare spots,etc. to keep rust down. I finally have everything ruffed in and would like to put a coat of primer over it. My question is what should I prime with and how much of the old primer do I need to sand off. All? Most? I have been looking at going with the Cross Fire line form Napa. They have the CP400 Epoxy Primer and the 15221 2K primer on hand. Any and all suggestions are welcome and thanks for the help!

I would recomend that you remove the rattle can primer using 180 grit paper. If you can't get it all off that's OK, as long as the vast majority is off. I don't know the Cross Fire line of products but an etching primer does require a good surface for it to bite into and rattle can primer will reduce it's general effectiveness.

A good epoxy primer is an excellent idea because the epoxy with thoroughly seal the body surface from moisture and is very durable. One thing to consider, using a High Build Primer will build up a good thickness and will fill most small imperfections such as sanding scratches or tiny nicks.

Good Luck and have a good one!

Thanks for the reply. Would you use a DA or hand sand it? Has anyone used the Cross Fire line? If not can anyone recommend another brand that won't break the bank...

Use a DA to sand. Put your money in the epoxy primer you will never be sorry. The paint job starts with prep. You can use cheep paint and still look good but if you use cheep primer it will show. Just my 02.
