I've clear coated most of the polished aluminium, smaller bits, just have the wheels to finish. Unfortunately, the clear coat dulls the shine quite a bit. Funny stuff to spray on polished aluminium: I had to spray a very light coat first, give it a few minutes then hit it again with a heavier coat so the paint would pool and flatten out. Still a bit of orange peel though, particularly on the triangular engine mount. The clear coat doesn't behave the same over painted surfaces, just polished aluminium, very disappointed in the finish. I may not clear coat the wheels as they'd be hard to get the clear to pool, there's a very fine line between pooling and a run. Float coating seems to just run and build up on the edges.
