well i wrote that thread based on the fact that marine tex adhered to metal extremely well...where as before i was skim coating with bondo (resin based) then #criss cross scratching it before it hardened and then applying fiberglass cloth / resin to fix anything metal. Doing anything fiberglass is a no brainer and it lasts forever but with the moisture retention of bondo (porosity) the repairs to anything metal rust out again.So its nice to have a different and better product for metal in my selection of tools.
