Remove the section of triple tree that fits into the frame.

I use 4000 grit sanding pad to remove the orange peel. Then I use 3M Rubbing Compound Professional Formula followed up with 3M Finish restorer. Both of these are a liquid and come in 8 oz bottles. I got them from Walmart but most Auto store should carry them.
My paint finishes are not Show winning quality but I think they look great on my shelf.
