self etching primer vs sandable primer vs normal primer for painting alloy

[sssgood]

ok guys I wanted to paint the stock alloy on my 95 camry black, might not be that pretty but meh. anyway so doing a bit of research I learned that first I clean the rim, then put primer on it, then 1-2 layers of paint, then 2 layers of clear coat (to make it shiny ). but when I went to get the primer there were 3 types, one was sandable, then self etching, then the normal cheap one. so my question is which one should I get? and I want the paint to stay like at least 1.5 years, so is there something else i should put on (like I heard paint doesnt stick to alloy very well),

thanks in advance

Theres allot to it these days. . .

Bare metal surfaces that cant be sanded easily is where self etching primer is best. What condition are they in?

You still need to sand chips and nicks out, it won't fill the holes so those need filled too. You also need to get the wheel spotless clean. Depending on its condition you may consider bead blasting to get the surface uniform. Alloy's and salt can take off and corrode depending on where you live and condition they're in. Bead blasting with clean beads will solve this. Don't sand blast with salty sand. Self defeating. . .

Are you looking at base coat clear coats? Cause now you need a good gun and clean air to spray them with. This can all add up. . .

Keep reading, lots to learn. Drop a note if ya need some input.

they are in pretty good condition, just cleaned them up real well (there was some brake dust). and what's bead blasting?
