I wouldn't recommend ceramic over matte, it would almost convert it to satin. I have really positive experience with Matte Jet Seal from Chemical guys (once every 3 months - applies within an hour) and regular wipe using Meticulous Matte Quick detailer and microfiber. It does offer really good...
Decided on matte black Avery Dennison, Beyond Slick in-house developed patterns, did not remove the base of the fender flares, just the cover. It is approx 0.25inches in regardless. Did it at my warehouse in Orange County.
Took me 6.5 hours after prep. What are your thoughts?
