Good luck. Please don't use the Rustolium primer. Like Ed said, if
you have to use the LustreKote, then use their primer. Rustolium
is only used by painters that get paid by the hour while they sit
and wait for it to dry. The only top coat that will really stick to it is
their own color paints and two weeks later you can take your
fingernail and scrape off the color and primer. Believe me, I've
used all the types of paints as part of my job.
Oops, I missed your last why? The Rustolium primer is like an oil
base paint where the acrylic lacquers won't adhere to it as I said
their own colors will. As you mentioned last month that your not
after a contest winning finish, but I hate to see you head down a
road of grief. I recently traded for a couple of planes that the guy
loved Rustolium primer too. Now I'm trying to sand smooth the
runs and crackle finish. I sand a little -it balls up- cuss him a little-
sand and ball -- wet sand -- cuss him, da plane and him some more. After a week of getting it smooth, I'm ready for standard
AUTO SANDABLE PRIMER. (white or light gray)
