This will be my first try at bodywork, so bear with me. I plan to start fixing some dents in my sheetmetal soon, I plan to grind down to metal, then use a stud welder to pull, then lay down some filler to smooth it out. It will take me a few months I'm sure to get this done (in high humidity).
Is there a recommended rattle can product I can use to keep each patch "preserved" without rusting while I work my way around the car. I will need to paint over it later, but I don't have a place to spray two part paint right now.

Thanks

I really have not found any rattle can primer that can hold up real well, but I am no expert in this field

Ah...so many pedestrians, so little time...

I agree about rattle can. Im in the middle of bare metal showing on mine too. I would just find a gun a spray it with 2part primer. If it looks bad or gets dust at least it will be sealed up and you can resand when you find a booth. You wont want spray bomb under your primer any ways.

Just go to an auto body supply place and get some rattle can etching primer to cover for now.

go to a body supply store and get some vari-prime. you can brush it on and remove it later with laquer thinner. may take several coats to get the desired coverage. i've done 2 cars this way and it was several years between start and final paint and body work. i stripped them to bare metal then coated them with a brush. maybe some pics later, i don't have them on this computer. dave

If this is going to be temporary then I would spray the areas with Rustoleum or similar NON-PRIMER. When you're ready for your final finish, sand it all off and prime properly. Primers don't seal out moisture, a rattle can enamel will.

Two coats of some good self-etch in a spray can will be fine until your ready to reprime/repaint. I have some on my car.

For small areas buy some real primer and spray in on with a Preval.

The reducer required to thin out autobody paint + primers can cause lifting problems when putting it over top of bomb can products.

none of acid etching primers have moisture blocking properties, I'd suggest buying some epoxy primer, do your metal work,brush on epoxy and then do your filler over that, this way the metal will be protected.

Etching primer does nothing except provide a chemical bite for your primer. It is very translucent and has no sealing properties. If your using it seal your body work, you're gonna have problems.

get some PPG epoxy primer. use the 401 catalyst when you mix it. when you mix epoxy with 401 you can use it for a week without it catalysing. then mix a small amount in a sealed container, spray your small spots, then pour it back into the container and rinse the sprayer. if you put the mixed epoxy in the fridge it should be good to spray for several weeks.

Some good idea's, I will try to use a "real" primer, even if I have to brush it on.

finally able to get to the computer my pics are on. 1st pic you see the door jamb is stripped ready to brush on the vari-prime. the quater is done but you can see i've reworked the wheel-well metal wise but not added any filler yet. see the dents?. i was waiting at that point to see who was going to do the final paint, me or someone else and usally paint guys want do do their own filler work so they know what is there. tech at the paint store said he wouldn't recommend driving or exposing the car to weather with just the vari-prime on but you can see that wasn't happening soon, lol

2nd pic shows the other side at a later date and i've strpped the roof by then. as stated earlier, when paint time came the paint guy da'ed the body and i washed down the places he could't get to with laquer thinner to remove the vari-prime.

This whole post has got me thinking differently now. I had been using etching primer for temporary protection and then removing it at a later time to spray with epoxy. From now on I'm just going to spray with epoxy and be done with it. I'm going to give this thing a try for the smaller areas...

Urethane primer is not porous like the others.

Yeah, it's got a smallblock.
