is there a certain amount of time thats TOO LONG to wait after you lay down your color coat or clear coat when your waiting for it to dry so you can buff / hit it with high grits?

or is it the longer the better?
+ extra; how dry should it be , is there formula that takes temperature + time into account for this?

Once its painted in theory it can be baked then flattened and polished as soon as its cooled down, but you can flatten and polish a car thats still got the factory paint - its just alot tougher and more work. Personally i prefer waiting till its properly hardened than trying to rush it when the paints still soft

properly hardened ... generally meaning..? 24hrs?

thnks

i always get to excited to start sanding my color coat on anything i do and also getting carried away with my wet coats.

so when i sand early i end up sanding wet paint. :thumbdown:

I was trying to get an ideas of making sure my paint is dry. as for laying down a wet coat i will just figure out over time.

Depending on the weather and temperature I generally wait about 2 weeks to make sure that everything has settled and hardened like it has supposed to. You can wait longer or shorter but I have found that 2 weeks (again depending on temperature) is a good safe zone.

if you use a medium speed drying clear like we do at my job you can buff it in a few hours with the proper heating and a good temperature (we paint cars outside with no tents just spray guns and shop heaters) but the best length of time for clear to fully cure is usually 1week.

Like I said it really depends. But 2 weeks is my safe zone.
