I have been spraying DBU & DBC since they were first introduced , I know all the quirks and pit falls of both , been a PPG guy for 30 years .
Been to all the PPG paint schools through the years to keep my all levels
certifications for the GM dealerships and the current one I work for now up to date .
IMO you cant find an easier product to spray then DBU.
I still prefer DBU , its quicker , easier to repair , better color matches , NO lift cycle , ( but have seen it lift , if it the clear edge has been broken , and had to re-spot to soon , happens when you have Conan the barbarian body men ) The DRR reactive reducer is like a catalyzed base reducer and will lock the metallic & pearls , so mottling & color shifting is nill when clear is applied . Its why after a few hours to a day ( temps will determine longevity ) it turns to jello . It will lay flat if reduced and sprayed correctly .
DBC uses the same reducer as their clears , so it makes a paint job a tad cheaper to spray . But it is more temperamental in the clear application , as if its still a tad wet , it will mottle and color shift . It does have a lift cycle if you dont use the catalyst additive . ( I think its DX 61 been awhile since I used it , its the only way I will spray DBC .)
DRR reducer is only good for 1-3 months after opened depending on the Storage temps , you were lucky the DBU didnt turn to cottage cheese when you reduced the base . Have had it happen with old DRR reducer . So count your blessings as the Paint Gods were on your side ..LOL

The BC your referring to ? Are you talking the PPG's Global line ?
I demoed it several years ago , and liked the wet on wet application , as it makes for faster turn around time in a production shop , but they still didnt have the color matches down to my liking .

I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
