Looking for a part or what it is called..

Sticks well to a clean surface, a little tougher than plastigrip, will insulate and it is pliable (like heat shrink tubing) when dry. I have used it between metal plates to form a electrically neutral surface when I installed an hydrogen generator on my kids car and the stupid pwm (pulse width modulator) for adjusting the amp draw had to be negative neutral (like using a positive ground item on a neg ground vehicle) Still working great after 2 yrs of vibration. The price isnot to bad either around 8 for 2 oz. I love the stuff for putting around nicked wires that just have insulation nicks. Hope it helped. Can find it at grainger or electrical sections of better hardware stores.
Just reread all the posts and am starting to think the abs idea is better. Well the post I am putting up gave me a chance to use my brain again. LOL
