I endorse the use of Evercoat body fillers. Been using them for years. I like "Z-Grip" the best. No pin holes and sands out real nice and feathers out real nice. I've also used "LightWeight" but don't like the way it sands. "Rage" is great, especially if you wait a long time before sanding. The longer it sits the easier it is to sand. With regards to being "cheap" when it comes to buying body filler I consider how much filler is going to be used and what is the cost differential. So at the end of the job you spent $80-$100 more total for the body filler,and it was easier to work with, and the body work looks better. Is the extra money worth spending? I think so.
