What you want is what the electrical guys call "potting compound". Comes in silicone and epoxy and is used to "pot" or seal electrical components. Comes in conducting and nonconducting. We want nonconducting.
Some types have a self leveling feature (low viscoscity) so it will ooze across the board and create a level pool. This is what we want. Potting compounds used to be silicone, but epoxies are used a lot now. To my way of thinking, this is a 30 year old car and the potting compound may need to be removed later for another fix. Silicone is much easier to dig out than epoxy, so I would suggest silicone. Searching silicone potting compound prices turned up this linky for $18 a tube. Linky fixed Ken |
