We have a 50 chevy hardtop that is as rusty as they come. i figured this would be a good time to teach my son how to hammer out a few panels with just basic tools. most of the panels we made can be bought but if i got all the ones we need for the whole car it would run into the thousands. the total cost for the job so far is less than $100 bucks. the sheet metal for the center of the trunk was $54 on ebay. very basic but cheap. the rest of the metal came from a cougar roof and tahoe hood. seam sealer was $18 , the support chanels were $8 and metal for the frame was $12. hope this helps someone else who , like us, has more time than money . this is what we started with, pretty nasty ! first thing to do is make patterns out of cardboard to the size and shape needed for the repair using whats left of the trunk as a guide. after your happy with the fit of the pattern trace it out on the metal and cut. i use a nibbler, works the best and cuts clean. the yellow lines are the bend guide. we put it in a regular vice , took a body hammer and bent it into the shape we needed.
