Easy as I am a shade tree guy!
Using sandpaper too long! Get a new piece!!
Also not using coarse enough paper! I am always using 400 when I should be flattening the surface with 100 on a block. This adds WAY, WAY too many hours to your project.
Pushing too hard on my sanding blocks! Let the sandpaper do the work and you need to finesse the block not try to push it thru the panel so that it sands FAST!
Never use sandpaper with your hands IF at all possible. I know you must and I do too.
This feeds into knowing the difference between a smooth surface and a flat surface. You need flat first then smooth. I have produced many smooth but not flat panels!
As posted above way too many filler applications! I hate to see those "fried egg" patterns all over the car because of this! I don't follow the TV guys who coat the entire car with filler and go from there BUT I do need to spread the filler over a wider area.
This a subtle one and I did not learn this until years of using my SATA 2000 gun. When you read the term "production" gun that means it's a fire hose! Made for guys painting all day long and they need to move fast and make money. As a home guy I don't! I am moving to an Iwata LPH400 as that is a much slower gun and matches my speed WAY better! The SATA requires no mistakes and fast movements. Great for a pro terrible for an amateur.
