Epoxy primer in stages
Hey guys, hows everyone? Summer up here is finally more than rain (Ottawa, Ontario, Canada), and im starting to do more body work! (finally)

Anyways, I do not have the time or space or anything else to strip this whole car down, and epoxy it all at once. At this point im just cutting in and replaces panels one at a time. Just rough cut out the old 1/4 panel, drilled the wheel wells out and starting to clean it up, fitting new parts (yah im replacing alot of panels, the car is in horrible shape (1970 mustang fastback/Canadian winters)).

So what im wondering is:

Is it possible to work like this and spray some SPI (thinking of going with SPI) epoxy primer over the work i have done. Then go to another spot work on it, spray it, repeat.

What kind of problems am i going to have when the 2 sections meet, with seams in my epoxy and what not? Is this possible, or should i go with some dirt cheap rattle can primers then go back later, sand everything back off, and re-epoxy when ready to start the filler work?

Thanks guys!

Works fine for me
What you have in mind will work out just fine...Just remember that you will have to sand out the whole car..not down to metal..when you get around to painting..

SPI has a 7 day recoat window..after that it needs to be sanded..this is not an issue for most of us as we are going to sand it down anyway when we go to final..Just enough to "break the surface"

Just for the record what you are planning is what I am doing...

Doing it in stages is no problem, when your section is bumped, welded, sanded, and cleaned spray it with epoxy and move to the next panel or area. The only thing you need to do is scuff the older epoxy with a red scotchbrite pad before applying more epoxy or overlapping on the edges. Scuffing is fast and easy and will guarantee good adhesion.

Yep, actually a good way to do it, Put epoxy primer on as soon as possible so you don't have bare metal out in the open and getting moisture. And you can apply filler over the epoxy, just rough it up. Then once everything is done and epoxy sand it and apply your filler primer if needed, or paint if everything is that straight. If you have bodywork areas you are probably going to be spraying a urethane filler primer, plus it sands easier then epoxy primer does.

Talk to me once you decide to order the SPI, I can tell you exactly how to deal with customs. My shipment JUST today got over the border and it is actually not as difficult to get it through Barry and Jeff Skinner thought it would be. Still, there are some steps that I can help with which will make it MUCH less of a headache!

I am pretty much planning on doing what you are saying. Epoxying fenders and suck before I tackle the main body. Unfortunately mine is a 1946 Nash, so everything else must be painted at the same time! (Unibody)

Good luck! Talk you Barry if you are in doubt. He has been most helpful answering all my annoying emails ;)
