It's been so long since I've held a paint gun... I need some refreshing.
I know that ideally, wash-primer and primer-surfacer should be from the same paint system. Is that a hard and fast rule? I want to lay down a PPG wash-primer (1791 primer/1792 catylist) on bare metal and later coat it with an (unknown yet) brand of primer surfacer. My (often faulty) memory seems to tell me that wash-primer is pretty generic. Is there a signficant chance of bubbling or other incompatibility? -Rusty (IMG:http://www.914world.com/bbs2/html/emoticons/smoke.gif) |

With the rule changes and reformulations of paints...it depends on the area you live in...."I" would go talk to the paint supplier and ask them. Some primers and fillers are not available in metropolitian areas due to environmenatl regulations that have been forced on us by the State rule makers.
Ask the guy that is trianed at the factory for the "system" that is available in your area. Paints need to have the right undercoats to work right... Some newer paints can't be applied by the old B-18 Binks cup gun...you need an HVLP. |
