hi i have a problem that i need advice on. i am painting a car with nason fullbase. i got the base on perfectly. looked nice and smooth with 4 coats. i waited 2 hours and put one coat of clear on with slow acivator since it was 81 degrees here today. the first coat looked beautiful. after about 30 min i put the second coat on and after about 15 min it started lifting in spots. it looks like sand in the paint. what do you think is going on? is it possible i didnt wait long enough or too long between coats. the tech sheet says 7 to 10 min. i thought that was minimum time up to 24 hours.
i have only done the fenders and doors. going to wait until tomorrow to finish hoping that when its dryer it will work. here is another site i found that indicates i might have waited too long between clear coats. any ideas? thanks.
