really imma hafta try this....like is using a hair dryer on it for like lets say 6 mintutes then spray it on?

After the Black walnuts dropped from the trees and put 6 dents in my roof, I went to abra auto body and now there new PDR paintless dent repair, they told me about a new deal...they Hot glue something to the middle of the dent, and then have some sort of puller and work the dent out, so no drilling like before...6 dents, plus 1 in the deck lid..= $600.00
