Which primer?
Here in the next week I am going to pull the fenders,cowl and hood off of the 68. Drivers side fender will have to be replaced and I have a new one on the way. I am planning to get the surface rust blasted off of the parts. I cant afford to paint the truck right now. What do I need to have put on the parts to keep them from rusting?

Re: Which primer?
i have been reading good things about picklex 20. wipes on and keeps blasted parts from rusting as long as they are not out in the rain. just scuff when ready to prime. you are not supposed to use an etching primer on top of this though. most people use an epoxy over it.

You will have to use an epoxy sealer to keep it from rusting.

Re: Which primer?
Epoxy primer is great at keeping moisture out and creating a nice barrier coat, but if you DO get any pinholes in it that go to the metal, it does NOTHING for preventing rust from forming beneath the epoxy film. I use hardly ever use expoy primer anymore. Etchprimer is where its at for preventing rust. In your case I would use an etching filler. Martin Senour has an etching filler that is cheap and uses an easy 1:1 mix ratio AND it is directly top-coatable. If you are just looking to protect it and are planning on using a good 2K primer down the road, I would just use a vinyl wash etch primer.sprays easy, protects and when it comes time to use a good primer just wipe it down with the proper cleaning agents.

Re: Which primer?
Dupont has a new primer-sealer out that is similar to PPG DP-40 I prefer Dupont myself but it is $140 a gallon. My years of painting and refinishing experience has certainly confirmed you get what you pay for! Nice thing about this new Primer-sealer when youre ready to paint or rework you just respray a light bonding coat no sanding or scratch pad needed,then spray on epoxy fill primer ,block sand reseal and top coat. Dont let anyone kid you a quality paint job will be a major investment if you have it done right!

Re: Which primer?
Key point if you're not painting right away is that you need a primer/sealer otherwise the primer will not hold up. I'm pretty much a one-trick-pony here, not an experienced painter, but I've been using PPG DPLF mixed as a primer sealer and it's worked out great for me. It was easy to put on, has held up very well - even looks pretty decent Agreed that it ain't cheap, but neither is having all your stuff blasted again.
My CarDomain link below has some more information and links. Head to your local paint shop, they'll help you review the options and prices and make the right choice. |

Re: Which primer?
I use velva seal from Dupont. It is strain and shoot, no mixing. Any sealing primer is what you need.
