I use what ever my dad gives me for free he sells high end paint and body material supples to body shops I get some really good stuff, the stuff i have now is a paint sealer and wax, i usually get to test everything and let him know how it works, this stuff has to set up on a cool car for 45 minutes and it makes the paint look like you just clear coated it.. makes the car look wet its great stuff.. also have some other paint Rejuvenating stuff that is unfreaking believable… I should post some pics if I ever get them back of my friends mustang 89 gt it was black and the paint was so dull, put this stuff on it, Have no clue who makes it because half the stuff I get is in un marked containers because its just samples and tests products but it made the paint look new.. and you didn’t have to buff the car or anything.. crazy, crazy stuff
