don`t use silica based products
McKee`s makes a spray for matte/vinyl
I have celeste Dettaglio from chemical guys its nice there buy way too expensive..i got it as a mystery gift on an order a long time ago
I`ve also used polish angel rapidwaxx on a matte surface and use it on my spoiler and vinyl decals on hood
Poorboy`s spray and wipe is good there too or McKee`s 914 rw but neither leave protection
I have gyeon q2 matte coating and matte cure but never used them
if I had to choose od go with spray and wipe for maintenance and rapidwaxx for protection on matte/satin
the McKee`s vinyl stuff is really hard not to recommend as one product only though
