yeah..have bought some white and some red paint few days..now find some time and energy to sand

for interior..im painting black..2 layer of paint or 1 layer + 1 layer clearcoat?

wanted a tough paintjob that wont chip off easily

i did the exact same for my case.

1. tape off, fill, or cover any screw holes (once painted can be a pain to clean out
2. tape off anything that u dont want painted (duh)
3. Sand. First with 100-120 grit paper, then finish with 220 or higher (i wouldn't go above 320 grit)
4. Clean surface with varasol, paint thinner or minieral spirits
5. Prime. Use a decent primer grey pretty much works great for any color. Start off with one light coat, then apply a second, and so forth till everything is covered evenly.
6. Sand again this time with 400 grit, just lightly though, to smooth off the primer. clean surface after
7. Paint. Again best results if you start with one light layer, and go on from there.
8. Inspect finish, if there are any runs or spots lightly sand with high grit paper and apply another layer.
9. Apply clear coat, Max 2-3 coats, wet sand before last coat. anymore than 2-3 coats of clear will make it to thick and the paint with chip off with the clear if scratched or chipped.

for brushed aluminum, no need for acids, just sand properly (i did all by hand, really don't need powersander) and use the right primer. I recommend Tremclad enamel paint. If applied with high density foam roller you can get a really nice finish, if u want a mirror reflection, then wetsand and buff with hightspeed polishter with turtle wax polish.

can also get metallic flakes at the local arts n craft store and add to the paint for added "pop" to the finish.

hope that helps.
i think.
