I tried out Opti-Seal
from Optimum Car Care Products. I was looking for a way to help protect my matte paint job and Harold told me about Opti-Seal. I gave it a test and their was no fading or discoloration at all. So today I tried it on the entire car and wow what a difference! The first thing I noticed was the fact that everything sort of slides right off. Dust just sort of slides off whereas dust would settle within an hour or so. Just use a foam applicator pad and apply the Opti-Seal. You only need a little bit... one squirt should be plenty... and it will coat a whole panel. If you see it start to streak, you have gone too much, but clean-up is easy. Just use a clean dry microfiber towel and wipe it off... No problem.
