The glazing putty, is it air dry or catalyzed, IE: do you mix with hardner?

No it's just the air dry Bondo brand glazing/spot putty the red stuff

Right....they also make it where you add hardener....but you shouldn't need it with primer. Just don't put primer down too wet and heavy- dust 2-3 light coats on and you should be Ok.

It has a hardner like bondo but easy to sand and spread drys fast also get a 3m rubber squeegee use lacquer thinner to clean the spreader before it hardens

I’ve had trouble with that spot putty and rustoleum primer. I use Rustoleum 2x. I wound up sanding off the primer in those areas. Add spot putty, let dry, sand, and then sit for a couple days. Or you could just use epoxy and micro balloons. This won’t clash with the primer. Thoroughly wipe that area down then try to reprime. Then, let the primer cure for 4-5 days. Lightly wet sand. Then spray color. Then add graphics etc and cure another 4-5 days. Then clear . What you save in money quickly gets eaten up in time and general grief. Next paint job will be good auto paint put into cans for colors then shoot clear with a gun. I don’t like getting out all that spray equipment but the product is just better. Anyway, good luck.

Cure times are most likely the problem.

Rustoleum will wrinkle if put over coats that didn't fully cure yet. Once it dries then you need a few days for it to be hard enough to recoat if the previous coats were heavy especially.

Rustoleum is enamel and has the highest chance of occurring over most other types.

Very common occurence.

Stop playing with rattle can stuff!!
Strip it down to bare epoxy glass.
Wash, scrub with scotch Brite & simple green. Wipe with prep solvent.
Get a inexpensive spray gun.
Prime with an epoxy primer. AFTER wiping down with prep solvent.
After a GOOD primer you can rattle can color....
But seal it with a good 2K clear coat.

I've experienced this on rockets. Was it the same paint can that is crinkling? The conclusion I came to after researching it on the rocketry and model airplane forums is that different batches of Rust-Oleum and Krylon could have different propellant and thinners depending on where and when they where manufactured causing this, unless you wait like 3 months to re-coat.

I use either paint from Wings West and clear coat it with Spray Max clear epoxy (small things like cowls) or Klass Koat for bigger ones......

Gotta wipe it down with acetone (or at least alcohol) before you spray.
