Clear Bra - simple sealant/wax/or even a light polsihing to remove the light swirls. When I say "light polisihing" I mean very light if using a PC. Use the white pad followed up by the black.
Clear bra material is stronger now than in the past and is able to withstand some polishing. Use a credit card to remove residue from the edges ......... preferably a gold card if available. ;-)
I order everything from Chemical Guys and haven't been satisfied with the majority of products I've used. Lots of trial & error along the way.
I use the Natural Matte Finish for exterior trim protection including tires. The finish leaves a beautiful finish without the exhausting shine.
