You get what you pay for using "Bondo". That crap will shrink and show! Your best option is the Evercoat Metal/Final glaze. It will blend with the featheredge with no issues. Its in a white squeeze bottle with green label. I would have to go out to the shop and get the number. All auto paint supply stores carry it. Its around $26 a bottle but I have never had a recheck from it in 10 years of using it in the production side. This coming from a Master CRRT Tech. Should not fill more than 3/32nds. Take the time to pull dents. Well worth the time and effort. I am not much on a stud gun, I prefer my Eagle II machine.
