I went to the body shop supply store to buy the supplies for buffing... I quickly became depressed. The guy there told me that after painting, I have about 2 days to do buffing, but after that the paint goes through a hardening process and I won't be able to buff for another 2 weeks. This was awful news, but this guy is not always 100% correct. The paint is PPG Concept single stage, and I painted the car on the 23rd. That's 5 days ago.

They say after 3 days is fine. If you don't buff cars often, A week is fine. The finish gets a little hard as the days go by which means it's a little harder to sand and burn through because the paint is harder.

The guy is blowin smoke!
I find I get better finishes the harder (cured) the paint is

Well I just want to make sure. He said it would be extremely difficult to buff scratches out, and that if I didn't want the 2 weeks, the paint would dull quickly in its life. I have to be 100% sure everything is okay before I try this.

Paint starts curing the second it becomes atomized out of the gun, stages from flashing to tacky and hard to the touch, continues curing until final hardness is reached in approx 30-90 days depending on paint, temperature, humidity, ect. I do not spray PPG myself, but have never heard of a "two week" period "or the paint will dull" I do know that a single stage paint will require more maintenance than two stage ( cleared ) Was there a gloss hardener or catalyst applied into the paint??
I've cut and strike-out all my paint-jobs within a 24 hr period or later and have never seen a concern at any date afterward. If someone else knows something we dont please post it so we all can get more educated on this.
Thanks, Rich
