according to chargers method, 2 coats, wetsand, 2 coats, wetsand process, are these 2 coats back to back? I mean after you apply 1 coat, you follow immediatly with another coat?



NO. You need to allow the first coat to dry and cure properly before slapping on the next coat. If you slap on the second coat before the first one properly cures, you will end up trapping the lower layer while it is curing - which will lead to the paint wrinkling into the orange peel effect. Normally you just need to allow about 1 day for the coat to dry ( with times varying according to the temperature you are working in and the amount of humidity in the air.

Colder temperatures - give it extra drying time
Warmer temperatures - 18 to 24 hours
Very humid - give it a little extra time
Very dry air conditions - 18 - 24 hours
