Extending the life......

[mwaynebennett]

I bought some Plasti Dip liquid and dipped my Harbor Freight pin-pointer tip into it giving it several coats. This added a protective shield to the end that gets scraped though the spoils of an excavated hole and gets plowed into the sides of excavated holes. The layer is perhaps only 0.020" thick and it is tough and waterproof also.

I also bought a can of spray Plasti Dip in the color black and sprayed it to the bottom and side surfaces of my 8" search coil. It it imperceivable once dry and also is perhaps only 0.015" thick and waterproof. It seems to make a heck of a lot more sense treating the search coil this way as opposed to buying a molder cover for it to protect it.

It never crossed my mind to try something like that. Where did you get the idea and are there others who have had any results to report? I would imagine the weight increase would be little noticed. Because of all the jagged rock around here, I've thought of using over priced plastic coil covers but maybe this is a better way to go. I would think the open coil and a bottom cover would act like a dust, dirt, and debris trap making for cleaning problems.

I just made up the idea. I have used Plasti Dip in other applications and thought that applying a few grams of tough rubber-like material to the bottom and side surfaces would extend the life of the coil. The pin pointer has such a tiny amount that it is almost imperceivable when looking at it. Plus the PP is now waterproof. I never thrust the PP into water looking for a target until I added the Plasti-Dip. I imagine that the spray Plasti Dip improves the waterproofness of the coil especially if a tiny shot is applied where the cable enters the coil housing.

As I recall, this stuff is a bit rubber like so besides scrape and scuff protection, maybe it will dampen some of the shock from rock hits. I can't think of any reason it would hurt anything unless it melts the plastic coil material and could void a warranty if you have one. Your going to have to run it through a working out and let us know how it works. I've heard of guys finding plastic bowls that fit and modify them to stay attached to their coils. There may be a number of things that would work but I think you have a good idea going there.

Plasti color spray bedliner in cans at walmart is better for coils. Plasti dip can rub or peel off. It is good for digger handles.

I was using the plasti dip spray can and I was getting peeling. Will try bedliner spray....Thanks
