need final sanding advice. was created by ironslave
I Painted my bike today, tank and side covers. My first paint job and it has some problems.

I oversprayed and got a big sag in one spot, I sanded it down and resprayed in that area and it looks different from the rest of the paint. It is flatter. but I am not going to fix it because I've gone through enough paint already.

I used the Duplicolor Metalcast system using all duplicator products. Sandable Primer followed by Metallic base coat followed by metal cast orange clear coat. It looks pretty good but the coats were uneven, It looks cool but the final product is uneven with some orange peel. I sanded it all down with 400 followed by 1000 and painted again. The orange peel is much less pronounce but the coats are still kind of bumpy.

What would you suggest I do to smooth it out. I am afraid I will either sand through the paint or make it cloudy all the way down to 2000 grit. How long should I wait before I sand it and how should I sand it to polish up the surface.

I read that this paint should be able to be applied with no sanding at all with the exception of the prep having 400 grit which I did do.

I will leave it before I ruin it. The paint is hard to come by here and I had to order it.

here is a pic of the bike back together. The paint is so uneven on the tank it isn't even funny. It will do as it is way better then the flat black primer that was rubbing everywhere. It really pops orange and metallic in the full sun though.

what ended up making this weird is how nice the tank looks in the garage. It looks exactly like the side panel.
I think i should put on a few more coats to even out the color, thats what I did to the side panels and it fixed them.

What should I paint next?

What Old Man Rock said. That will help you through the process.

I actually had a friend give me a 3000 grit sanding sponge. Was firm and I was able to sand a nice even surface on my tank to prep the clear before polishing it.

As far as the basecoat, follow what Old Man Rock said and it should help you through it.

thanks for the advice, from what you said i was moving across too fast. never had any runs except where i accidentally stopped movement too soon. I have to get more metal cast for the tank as it isn't as dark as the side panels, the side panels look excellent though!
