So how long can I leave this on my truck before painting 🤔

This stuff is very tough to sand it is almost like stand alone paint very durable kinda surprised me no fingerprint transfer after it dried so I dont think it matters much. I left mine on for a week before I got around to painting I just ran a clean new terrycloth towel & normal prep and my flat black topcoat is fine a year later

Can I paint my handgun with it? It’s old and it got some rust I want to prevent it

I wold not maybe some 3000 grit depending 5000 or higher or even lower grit. test in a small area underneath or a hidden area under the grip/stock if its super light rust might get it clean then oil it or get some blue steel for guns and re blue it. All depends on bad the rust is check inside the action barrel or better yet get a gun Smith to look at it there better ways than this rustoleum

Can i use this on aluminum? Ford makes its hoods from aluminium and I'm spot painting some of the rusted areas.

Leaves a fine surface ready to receive paint.

Sprays well and fills small lines and cracks to ready the surface for the finish paint. Definitely produces a better final product than not using it.
