Temporary paint?

Post by vandor » Sat Oct 12, 2019 2:40 pm

OK, so I have a Fiat that was sanded down to bare metal and then painted with primer. I just got done with most of the rust repair and now it's time for bodywork. That will take a while, but in the meanwhile I'd like to take the car on a weekend trip.
Is there some paint I can paint it with (think spray paint in a can) that will protect it from water/humidity, but will be easy to sand off once I start on the bodywork? Or is there a primer that is waterproof?

Thanks in advance.

Epoxy primer will seal metal surfaces from moisture indefinitely, sands easily and can go over some but not all paint types. But two part and not particularly cheap or convenient. Eastwood now carries it in special self mixing aerosol spray cans.

My current X and previous X were painted with standard Rustoleum spray paint. Sunrise red happens to be almost a perfect match to the red paint on the X. When ready to do the real paint, you can use it as a guide coat for sanding.

I sanded the car with 400 wet sand, did a good job of masking and was done in a day. Takes several days to get real hard but I was driving the car the next day after I painted it. My temporary paint jobs tend to remain for years, as I simply don't have money for real paint jobs.

Carl, I heard the Rustoleum is very difficult to sand off once cured, do you know if that is true?

Thank for the suggestions, both of you.

No harder than the paint that Fiat put on in the first place. If you have time, buy a can, shoot a piece of metal and see. I think that stuff takes a year to fully cure!

Rustoleum used to be fish oil based (at least the Rusty Metal Primer was) which you do not want under automotive paint.

Not that I'm second-guessing Carl (which I guess I am) - but before I used it I would call Rustoleum tech support and discuss.

oooh, that is an interesting twist. I've been seriously considering some Carl-spec red rustoleum as a temporary cover as a scuff/cover my '85 X1/9 that has plenty of paint on it, but was painted with enough metal flake to make a bass boat embarrassed.

Rustoleum used to be a line of products for protecting metal outdoors. The original base was menhaden fish oil. Today Rustoleum is simply a paint brand, mostly water based and low VOC's. Don't assume any Rustoleum branded paint is still based on their original formulas and don't assume that what's sold in pint and quart tins bears any relationship to what's loaded in their aerosols.

Locally Rustoleum dominates the ready to use paint shelves of our big box home stores. You pay a premium for dealing with an auto paint store but you are far more likely to get the right paint for your specific car needs there.

Thanks Richard for clearing that up - I wasn't aware of the recent formulations

If it were me I'd go with some of that "fast dry" Krylon
