I have a problem, two stage paint ppg sanded thru clear coat to base in five or six spots fixing some problems, not sure how to fix. Can or should i use a primer sealer on the places i went thru. If i go with base i get a halo will this happen with a primer sealer ? Wasnt sure where to put this sorry if its in wrong place.:confused:

The only way that has ever worked for me is a couple of coats of water borne primer. Then base and reclear. I do not use PPG for that very reason.
 
Activating the base makes a big difference on repair sensitivity. Reducer selection can also make a big difference-what reducer are you using-some are really harsh and will fry any thin edge. Application makes a big diff too-you need light coats of base with a LOT of flash time between coats, good temps are a must. The worst bases for repair-ability weren't PPG.
 
The paints almost a year old and i have ppg 885 reducer on the shelf. should i get a slower/faster reducer? the car is in a heated area the metal is at about 70 F'
By alot of flash would 1-2 hous or more? to much to little?
 
870 would be best but 885 will work and be a better choice the 860.
Trick is at the broken through areas just do a spot med to light coat, 30 minutes more do a second, continue until the spot is covered the finish basing the panel.
Flash between coats is critical and first time you rush one coat, it will act with vengeance. Not that I have ever rushed one and messed it up. LOL
 
Thanks Barry,

At this point if the 870 is my best bet I'll pick up a gallon. And take my time.
 
I'd think that with a year old paint job would be OK from a sensitivity point of view. A little primer spot over the sand-throughs would help ensure that you don't see any "ringing" or "bullseyes" later in the finished product, but a lot of times a guy can get away with spotting color directly over the sand-throughs.
 
Hey crashtech,

Good point about it showing up later, that light bulb hadn't come on yet. I have some 6520-1 regular primer on the shelf. would it still be wise to go with multiple light coats?
 
If Barry thinks you can get away with spotting base directly over the sand-throughs, you probably can. But I might want to spot a little primer just to be safe, if it is something that needs to be really nice.
 
Yeah It has to be nice. I think i will spot a little primer to be safe like you said. Plus i have everything to do that. my supplier is a 60 mile round trip to get the 870 i dont mind trip when im picking up alot of material, but just for a gallon of thinner only if i have to.
