This months HOT Rod mag has a article on paint and sheet metal prep very good one at that . One thing there discussing is a shrinking disc . From reading the mag this disc looks like the tool for straightning metal without intense heat . Iv'e seen a home made one also on a site i think was called Metal Shapers and it did a fantastic job also . This disc supposedly helps with the non use of plastic . The pick and dolly is still used to bring metal to a close shape then the disc is ran over and picked again .

I have a area on one of my fenders that feels like your rubbing your hand over a dozen eggs . Previous owner was a little to heavy with his tool . I can bring it back alot with some work but i was really interested in this shrinking disc just to see how far it would go . Also to see if no filler would have to be used . They said in Hot Rod that all that would be needed was some good fill and sand .

Anyone here ever use it and what would you guys think of this tool .
