I used to spray Rust Oleum for RC paint and occasionally for rockets.
It's good for RC as the original formula is fuel proof to 50% raw nitromethane.
It has gotten VERY inconsistent unfortunately.
I have switched back to expensive hobby brands due to those always being consistent.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
