Hello there.

I've been doing powder coating for over 4 years now and can give you some advice.To get a correct finish you will need to have as much bare metal as possible for the powder to cure correctly without starring up.Just re-working a product thats already been powder coated has trouble taking another coat of powder the second time round.

I keep seeing people put 15 minutes for curing.This is so wrong! Yes the cure temputure should be at min of 180c and max of 195c.At these temps you should cure the item for 30mins.Depending on the nature of the powder your using,most will react good to longer is better.Giving the paint a more gloss/metalic look.

Are you doing this at home or using a company?
