[QUOTE=Esser;31164]So I put too much so I had to sand a lot but i still managed to get low spots, must have been air pockets or something.

When using filler in small quantities, I usually spread it with a single edge razor blade. Actually it is a blade held in a window paint scraper handle. It usually takes a couple of applications - or more if the finish will be paint, but it minimizes the sanding part.
