single stage vs base coat clear

Please don't confuse OEM factory TSA (high bake) enamels to the refinish (air dry) alkyd enamels. They are miles apart in chemistry and workability. The same goes for OEM BC/CC systems to refinish BC/CC systems as there is no comparison what so ever. They may look the same in appearance because they are supposed to but it ends there.

Yes, the main reasons automotive paints in general have evolved is EPA legislation and durability, mostly EPA pushing for lower VOC's (volatile organic compounds).

Air dry refinish (single stage) enamels are fairly easy to spray as opposed to the refinish bc/cc systems because they have to be due to the human factor, meaning they are hand applied. The refinish BC/CC systems are a little harder to spray but not by a large margin and again there is also the human factor to consider.

OEM paint systems are painted in controlled conditions with automation and can be less forgiving. I've been in car plants where they were painting as many as 87 jobs an hour. It looked like a fast freight getting color on it.

OEM Lacquer systems should never have been invented because they are the worst for durability. But, they sprayed not too bad and polished up pretty decent and GM liked them.

Yes, All BC/CC systems are more durable than all single stage systems.


On a final note:

The refinish paints on the market today vary drastically in composition or chemistry (supplier to supplier). It does affect the workability of each product. I don't envy some of you painters out there that have to deal with this stuff on a daily basis.


And please protect yourselves when you are spraying paints, primers, etc.. That s_ _ t will kill you. I can't stress this enough. Some of you that are painting at home with your makeshift paint booths just make me cringe.
