just to help u out a bit idont no what colour ur spraying but the best way is to get ur garage realy warm get a couple of old car rad fans blowing down either side so the air is drawing the water out of the paint make sure each coat is dry if its not metalic u can still get solid colours in 2 pack p.s. dont add 10% of thinner like the reps say take it to about 5% hope this helps.
