Im about to replace my battery switches and realize there is a good amount of corrosion on most crimp connector, look like the wrong tool was use and damage the heat shrink tubing and allowed moisture to do its thing. So now I feel like I should replace all wire that are most expose to the elements, so basically everything from battery to main fuse box inside cabin. I really like the adhesive line heat shrink tubing, I have also used dielectric grease on several occasion but never together. Will it compromise the glue and negate its use or is it possible to use both? So what are you all thinking is the best approach for the longest lasting connection? Thanks for all input.
