Direct to Metal Filler Primer (DTM) is a non-isocyanate, chromate-free filler that may be applied directly to larger areas of bare metal without the need of first applying an etch filler. When used as a medium or high build filler (surfacer), DTM offers excellent corrosion protection on bare metal and OEM substrates, that easily sands by hand or machine. (Mix 4:1)
