I left a model to dry for about 20 hours, touched it with my finger and felt smooth and dry, so i put it in a plastic bag. 3 days later i take it out only to find the top of the model had a small imperfection.
I though the model was dry but it wasn't the part where the car and the plastic meet had joined togehter and messed up my paint. From now on i spray it and i cover it usually with the same box the kit came in for 4 days. and then spray clear on it.
