This is about the 4th bumper i have painted and never had a problem until this one.I painted the bumper bout two weeks ago and wet sanded it with 800,1000,1500,2000 and when i went to buff it out i got a white haze. I did notice some while i was wet sanding as well. the paint used is a ppg essentials single stage black. did it not have enough time to cure b4 i cut n buffed it??

 

hmmmm you get it when you wetsand and when you are buffing ,ive seen it when wetsanding ,but not much in single stage ,mostly in 2stage .i'm thinking its from not flashing it enough ,but then again i could be wrong ,but yeah thats whats i think

 

yea i have no idea. i followed the tech sheet did everything the same n dno just pissed..it started to appear when i wet sanded

 

OUCH.i personally never wetsand single stage, its just not a good idea in my opinion. But then again i use single stage once in a blue moon at the shop.Your basically sanding the pigments out of the top of the material but everyone has there own ways when it comes to dealing with paint. It looks as if theres some other crazy issue like some solvent reaction or water in there somewhere. quite possibly the reducer or activator is messing with the underlying material and reacting. Did you happen to seal the bumper before laying this paint ?

 

i used a shop line primer..but this was a brandie new bumper with that shittay primer on it..the first new bumper i did to..do uthink that primer could of affected the paint

 

looks like you sanded threw. single stage is ****.

 

It kinda does look like you sanded through. But it depends what shopline primer you used. Cus 2k surfacer from shopline is beige/brown. That looks like sealer under there.

 

you did sand thre just sand it down and start over. thats what you gonna have to do and use clear this time.
