This problem occurs exclusively when I use Rustoleum primer and Rustoleum
topcoats. That is one of the puzzlers here. Sorry if I was unclear- I
never use Rusty Metal Primer under anything that is intended for a final
topcoat with another manufacturers products. I have had compatibility
problems with other painting projects, usually when spraying Enamels over
Nitrocellulose or acrylic lacquer. But this question deals exclusively with
Rustoleum/rustoleum layers.
Thanks,

I have been told that a single "line" of finishing products should be used
from metal to final coat because of compatibility. Could this be a result
of an incompatibility between the Rustoleum and the final coat? It sounds
like the Rustoleum by itself is not a problem - even when overspraying with
another layer of Rustoleum products - but only when you use it as a primer
for other products.

Subject: General Rustoration, certainly lbc relevant.
In the course of restoring various lbc's, refinishing the hoodsticks,
prop-rods, spare tire wells, etc.. I have had some unexplained failures that
perhaps are not entirely my fault.
For years I have used Rustoleum enamel, largely because it seems fairly
durable and is readily available, and fairly inexpensive. Most of the time
it goes on fine, whether from aerosol or brush, even thinned and sprayed
with a gun. However, sometimes after starting with Rusty Metal primer, the
topcoats ( usually the 2nd) seem to react with the preceding layers to cause
the whole refinishing effort to wrinkle up and look more like 'Krinkle
Finish' than gloss black.
I have dutifully tried to follow the instructions ( not a natural act...)
and observe the correct waiting time between coats, air temps, clean
surfaces, etc. Still, at the most critical times, the paint will suddenly
erupt leaving me no alternative but to wipe the whole thing clean, or let it
dry and try to sand it back to some semi-textured state. I have called
Rustoleum on this problem, and they mumbled something like " sounds like
trapped thinner in the lower layers", which I do not readily believe. When
I spray a car with a good self etching primer and a couple of topcoats of
Centauri or Delstar Acrylic enamel, I have never seen a similar problem (
unless of course the surface is still covered with Simonize...) and I'm sure
that paint is full of trapped thinners...
Has anyone seen this problem, and if so, what magic words must I say
to avoid it? I sprayed my seat frames last night, and when I checked 'em
this AM, the 'grunge' had visited me yet again, just what you need on a
Monday morning....
Thanks
