If you want to read about the other quality PPG products just got to the Products Information tab and click on Paint Lines, then arrow down to Deltron , and read about the Base Coat & Concept 2K Single Stage products.

The if you want to read how to apply and what products to use under these fine products go to the left side drop down window & pull down and click on the Top Coats .

I Have used the BDU/DBC products since they came out in the late 80's with Global clear over it and never have any problems.
The concept is an excellent Single stage product and it can be sanded and buffed to an excellent shine . But it has a window where it buffs nice , then after about 4 days it rubs like cement. The sand scratches can be buffed out but it will take a little longer !
Global buffs like Butter and they have an excellent Single stage too, the price difference isnt that much .

Did you mean spraying a clearcoat over a single stage product?
Thanks.
