I ordered the trunk floor as a 3 pc. kit and frankly was amazed at the quality. The metal is a heavier gauge than OEM or other repro parts. Size and fit are perfect. The weld-thru primer is an added bonus, and you can in fact weld over it just fine. Better than the spray can type anyway. I've replaced a lot of sheetmetal on my 68 coupe, including the complete floor pan. I wish I would have gone with Dynacorn for main floor pan. and firewall extensions.
