I can tell ya now, for the cost of the extra coating, you can buy your own clearcoat lacquor* for like $7 bucks at O Rielly's or Autozone and save the cash for other things.
What color is your car Great_1?
White. I wasn't figuring on getting the clear coating just trying to gauge what the polished vs polish + clear would look like since they say the clear detracts from the finish a bit. Damn decision between glossy black and polished though
