I LOVE THIS LIST!!! >Greg Newell One technique is to alter the direction in which you spray for each coat. Say your first coat was sprayed in a horizontal orientation. The second coat could be 90 degrees to that. The third coat would be sprayed on the diagonal with the fourth coat 90 degree to that. This way you are not developing banding, or thicker ridges from overlap. By the same token, your sanding pattern between coats should follow similar alteration in sanding direction. With the water based material I have been spraying a 6 to 8" distance coats nicely. As an aside, a 'sag' is more likely to develop on a vertical surface if your spray pattern is horizontal. A benefit of a water based material is that the sag can be padded off and a light coat sprayed on top, then sanding the area smooth is not so laborious. The material is also somewhat flexible and a small drip could be removed with a razor blade and then sanded with a hard block.
