I've wet sanded centari with 1500 wet or dry sand paper and buffed. I just bought a small air buffer with about a 3" pad that works really neat.

Those are a lifesaver. I have the 3" wool pad, which I made a 2" aluminum back up disk for and mounted on an old 1/4" grinding chuck.That way it has a little more stiffness and a 2" black waffel pad that are worth ever penny paid for them.
If it's very bad,You may be better off 400 sanding and reshooting.Depending on how thick it is,you may cut thru and then your reshooting anyway. |

Finish sand with 2500 or finer and you should be able to easily hand rub it.

I used to paint with acrylic enamel a lot, and I've used the Centari.
It's a great product, very durable. I have rubbed out some colors successfully but ran into trouble with metalics and some other colors like blue. I kept getting uneven color changes when wet sanding it. The solution for me was to clear coat everything with a clear acrylic enamel. Sanding into a paint and exposing the metalic is usually a problem, but clearing and sanding/buffing the clear is an easy way to go. It may be to late for you to go this route now but if you get uneven patches from your color sanding I suggest you respray your color just enough to even it out then clearcoat it. You'll have a better job in the longrun. Maybe someone else on this site can say wether you can clearcoat over acrylic enamel with clear urethane, if you can, that would be even better. |

Dupont had what was called the 2000 pack that provided the compatible clear for use with centari. When I worked at a Ford dealership in the early 90's we used quite a bit of this stuff repainting peelers. Worked alright but nowhere near the durability of a urethane IMO.

Yes, be it Alkyd enamel or Acrylic enamel as long as you activate them with proper ratio and activater you can apply any clear over them in 4 hours. However it is always best to let the paint set overnight and than clear next day. The enamel does not need to be sand first. |
