Epoxy Primer

I just purchased a restoration project that someone had already started. The car had been stripped to the bare metal and some type of primer had been applied to prevent rust. What ever it is it does not have any build. They gave me a great deal of Epoxy primer and stated that was what they were going to apply next. The car needs to be blocked so should the Epoxy be the next step. Will the Epoxy give me any build. Can I block it and will it suffice as the final stage before paint? I have never used Epoxy so any advice would be appreciated.
No, epoxy won’t give you much build and it sands terribly. If they have already applied epoxy (and whatever dents and bodyfill work is complete) then you want to use a 2K urethane highbuild primer. Epoxy isn’t really designed to do this, some claim you can use them as a primer surfacer but it will take you about 10 times as long.
Since the customer insists on Epoxy somewhere in the process and it already has a coat of something on the bare metal, where shoud the epoxy be applied. Should urethane be sprayed and blocked and epoxy sprayed as the final coat before paint. Or is expoxy basicly useless at this point unless stripped down to metal and applied then. How would you suggest this project be accomplished at this stage since something has already been applied over the bare metal?
Well hopefully that’s epoxy primer on it now so you shouldn’t need to apply it under your urethane highbuild. You can use it as a sealer once your done sanding your urethane. It will provide a better foundation for your paint job. Use it wet-on-wet before your basecoat. What epoxy is it? (basf,ppg,spi,dupont…etc)
PP&G- When you say wet on wet you mean spray the base immediately after the epoxy. Do not wait unitl it drys and scuff. How many coats would you recommend of the epoxy
Wet on wet means spray your epoxy, let it flash and then spray your base without sanding the epoxy. I’d pull up the tech sheet for your epoxy from PPG’s website and it will give you all the necessary information such as how long to wait before putting the base on and how many coats you should use.
I finally got in touch with the guy who had done the work up to this point. He says that he sprayed etching primer from a rattle can to keep the car from rusting. That is what is on the car at this point. I am afraid that will turn into problems so I am considering removing what is on the vehicle now and starting from scratch.
That would be a good idea, it will likely wipe off with some paint thinner pretty easily. You could try sanding it off to.
