Title: Sealing Magnesium Cases
Post by: rokoncarl on December 28, 2006, 11:24:20 AM
Hello i am rebuilding a 73 jackpiner and was wondering what is the best was to seal the engine cases when the magnesium is starting to pit. Has anybody used Glyptal to seal the cases have used it on old harley cases to seal the porosity of the old cast cases with no problems. just wondering, thanks

Carl  First glas bead blast the cases really good and clean out the area pitted.  If the rotting is deep, mix up some JB weld and fill in the area.  Once cured, top off the entire area with Red Glyptal and that's it!  Good Luck!
