paint problems

[Kelly]

I have just started painting at a body shop for the first time in my life. I have been having a big problem with the MTK 9300 pre mixed Black Single Stage. The paint keeps dieing back and i don't know what is causing the problem? I've put extra coats on it, added more sealer to the first coat to cover better, and been trying different techniques but still havent been able to fix this problem. I also dont know the correct flash times for this product. I've just been winging it waiting 5-10 minutes until its somewhat dryer and tacky. Does anyone know what i'm doing wrong or how to correct this problem???

Are you reducing it?
Maybe over-reducing?

Are you useing a activator in it?
Is it an enamel or urethane?

If you're looking for a gloss finish you should be able to allow it to harden then sand and polish it to a high gloss. What type of paint is this? Lacquer, enamel, urethane? You can polish lacquer and hardened urethane.
