If you haven't used the torch method get some practice pieces. sometimes a body shop will let you have a practice fender from their recycle dumpster , tell them you will bring it back after you are done . My nephew used to stop by a body shop when walking home from Jr High. and watch thru the open door. The owner (one Man Shop) talked to him and answered a lot of questions, The Kid did some pretty good paint jobs before he got out of high school. Now He has a jewlery store, makes a lot of custom stuff and uses a mini torch to put it together.
