My friend ended up renting the rolling tool and heat gun from RollYourFender.Com - Home - Fast, Easy, & Affordable Professional Fender Lip Roller Rental. You pay $300, but get like $230 back once he receives the tool back. He even sends a return shipping label, so the $70 is total cost for everything. We did his car yesterday and it worked very well. We just kept the paint warm enough that you can hold your and on it, and we didn't get one single crack.
