Plasti-Paste™ is strong, durable and lightweight. The edges of the support shell can be sharp, so you should sand the Plasti-Paste™ to make handling safer and easier. Peel the Mold Max™ STROKE mold away from the original piece and seat the rubber mold into the support shell. The mold keys previously added will make aligning the mold with the shell very easy. Once seated, check the level across different axes.
