Hi, Installing a quarter panel using a central pneumatic flanging too. No proble making the offset flange, but when I lay the AMD quarter in place it appears to project out as such that if I grinded it smooth I would reduce the panel guage by about 50%?? Now that is not acceptable. Do I have the right tool to do the flanges? I would think that the sheetmetal overlay would be a tad bit deeper so there is room for a skimcoat of bondo?? I don't see any adjustments to change the offset. Are they available for different thibknesses? Is there a better tool and maybe mine is just cheap china crap? Any info would be appreciated.
