Silaprene Adhesive/Sealant experience

Acetic acid can also be 20%, 50%,100%, or anything in between, all which might surprise you with their effects on metals including stainless. Where does one buy the higher concentrations? I'm looking for something to apply to the aluminum stanchion bases in order to get loose the stainless bolts securing the stanchions to the bases. Might the higher concentrations of acetic be what I'm looking for? I would not slosh strong acid of any sort around anything on your boat as you never know where it will seep down and end up. I would first heat the bolt with one of those precision small burners you can attach to a can of gas. The bolt will expand but the aluminium will expand more and this should break the bond and make extraction easier. You can get really precise flames with the right sort of burner so it will concentrate the heat where you want it and not damage the surroundings.. |
