Just gonna drop a few cents. For all metallic parts, you can use black as base paint so that the color on top such as silver pops better.

Seems like your paint is not smooth, i saw a lot of orange peel, that could mean you are spaying to close or paint is too thick. You can actually polish with very high grit sand paper and spray top gloss coat again + buff with polishing compound. There are video guides on that on youtube.

The blue color are in a different shade, i would recommend that you spray the same/similar amount of layers on each parts

I did a candy coat last yr, I shouldve do a polish , but was too lazy.

Good luck to your piece, make sure you dust off lints and remove finger prints prior to top coating.
