sikkens is awesom stuff....i spray chromaclear everyday and its great stuff,7779s is myfavorite but i believe they took it off the market for the time being because of some problems,the 7900 series is good stuff for a really good price and uv protection.....chromapremier clearcoat is the freaking MONEY. that stuff is awesome. ppg makes great clear as well. just dont spray nason or omni-zero uv protection and its just a really hard clear that i have grown to hate. i saw someone mention that some clear isnt show quality clear, with initial spray i would agree with you, but if need be i can wetsand and buff the crappiest Nason clearcoat to shine like some spieshecker/sikkens clearcoat. its all about the painter and whats done afterwards,if anything. thats all my personal opinion. crappy materials can come out looking good with alot of finish work, but its alot nicer to just have to do it once.
this it the last thing i painted with nason base and clear..extra paint lying around, this was a tank for the owners bike. didnt wetsand or buff this at all. came out great and not a single piece of dirt. got lucky on that part.
chromaclear without ever touching the car with a piece of paper or buffer afterwards. this vette was blinding....
my daily after i got hit and had to repair, with chromaclear. its simply one of the best all around clears for price and quality.
