What kind of primer on top of blasted fresh bare metal
hey guys I just had my truck media blasted today (the whole thing) and now I need to find out what kind of primer to shoot over the metal so it dont rust. I have some metal work in spots and body work to do to the car also. My question is what kind of primer should i put on the car? Please let me know what brand and maybe part number or what its called. Also if you guys know what is the price on it please post for me.
thanks,
jimmy

Yes you want to use a good self etching primer. Its a good idea to decide what brands of paint supplies you are going to use on your project. Make shure that you use the same brands of etch primer, high build primer also called 2k, sealer and base/clear. So you dont run into compatabillity problems when using different brands of supplies for one project.
Good luck

Definitely self etching primer first over all bare metal surfaces! You don't need to put it on too thick though...a little goes a long way. Then i like 2k high build primer...2-3 good WET coats, wet sand, then primer sealer. After you get all that smoothed and looking good you can go ahead with your choice of color and clear coat depending on the finish you are looking for.

Depending on what media was used for blasting the sheet metal will need some prep before you prime it, if it was sand blasted you can just clean the metal then use a self etching epoxy primer, if it was soda blasted you will need to wash the sheet metal then D A sand with 80 grit paper minimum. The self etch primer I use is a southern polyurethane brand, after you spray it you have up to 7 days to do body work and or prime on top of it with out having to sand it. A 2 gallon sprayable kit costs about $135.00. The best thing to do is go to their website and do some reading. I believe other brands are about the same on the prep but I don't know what they cost.

If you're not going to top coat right away or still need to do some bondo work on your truck you should use an epoxy primer. Epoxy primer is the ony primer that I know of that will protect the metal for an extended period of time w/o being top coated and you can also use bondo on top of the epoxy primer. I'm doing my body work in stages, since I usually only get a chance to work on it on the weekend, so I use epoxy primer to protect my work. Once all the body work is down I will clean and sand the epoxy primer and then use a sealer/filler primer to cover the epoxy primer. Then block the body out before I top coat the truck w/ bc/cc.

I am following basically the same procedure as cujo for my long term project. I really cringe when I see people do lots of good work and then cover it with some garden variety primer. Most every primer is porous, but Epoxy Primer is something different and offers not only a seal, but also reacts very well with bare steel.

DuPont has a couple excellent 2 part primers, both excellent for bare metal or final sanding and both are relatively cheap in that regard... Let me correct myself, they're both made by Evercoat, I just get them from my local DuPont store. Slicksand and Featherfill are the names of them. They take a little while to dry but sand easily and are great for that final levelling of panels before paint and even as a starting point.

I disagree with the etch primer.... primarily because I always use the por metal ready that etches the metal and kills rust...same basic thing...AND...I like epoxy primer.
No sense is spending all that dough on etch primer.

The epoxy primer I get is not self etching.
I prefer an epoxy primmer over gray metal (media blasted), 2 coats. Then I spray 2 coats of 2K primmer different color, to make sure I don't sand into the epoxy.
