Rust-Oleum American Accents 2X Ultra Cover Flat Black Primer (327911 PRIMER BLACK)
Bought some K&S aluminum tubes. Sanded a piece with 400 grit sandpaper, cleaned it thoroughly with 91% isopropyl alcohol, sprayed Rust-Oleum primer, and let it cure for just over 24 hours. I did a fingernail scratch test, and it bonded surprisingly well. I've never had a consumer aerosol paint product bond so well to metal before. I have used brushed-on Model Master Acrylics before, which bonded extremely well to aluminum. Not even those "self-etching" spray cans worked this well.
