The Rust-Oleum textured paint came in from Amazon. When used on my test object, it had all the appearance of something painted in a dusty room, lots of uneven little bitty pieces of dust placed randomly. Not recommended.
A day or two later, I was doing a bit of inside the house touch up painting with a water based, flat white interior paint and thought, let's experiment. I mixed one ounce of the paint and one teaspoon new 40-80 grit glass beads to attempt a textured finish. I applied a test sample with a "not too good" brush to my test object. Then in the interest of science, I added more glass beads and applied another test sample next to the first using the same "not too good" brush (which also doubled as a mixing stick) for a comparison. After it dried, I sprayed the only white automotive paint I had (it was for seats), just to see what would happen when a light colored paint was applied over the textured paint, as in would it fill in the texture. The initial intent was to obtain a textured white that matched the white interior of 66 interior 62, blue/white, for the Rally Pac.
Pic 1 - My low profile black textured Rally Pac housing with the test object above. On the test object, the single teaspoon beads and one ounce of paint is the strip on the bottom, the second teaspoons of beads added above it, traces of the Rust-Oleum test above that, and a layer of the seat paint white on the right side for fill in (pieces of the unpainted test object appear randomly).
Pic 2 - The test object (hey, it worked. The remaining contents are safe in my 60 year old Philco fridge).
The next test stage is to use smaller size glass beads in the same white house paint. The smaller size beads are of two varieties, used glass beads from inside the bead blast cabinet, and used glass bead dust from the external vacuum tank.
