My engine mounts have light amounts of rust so I want to paint them. With out removing them.

Lots of nooks and crannies so I'll never be able to get them totally free of rust.

Any advice on products and procedures would be appreciated.

Will that stuff prevent any adjustment in the future on a mount? Its a sticky gummy paint if I recall correctly. Can you remove it a little with a wire brush if you need to turn a nut or bolt? Not sure how hard it is.

It is not sticky at all. As a matter of fact it dries hard as a rock. I would not put it on the threads. You will never get it off. But I do not see an issue with painting the rest of the mount with it. As far as the threads go you can get a product called chain wax that will seal moisture out of the threads. Its basically an aerosol wax that dries semi hard. It can be removed when needed. They sell it for motorcycle and industrial chains.

TL, You could also use Rust encapsulator from Eastwood. I have been using that stuff for a few years and it really does what it claims. I use the red just because it's a contrast and you can see any difference with time. I use it as a primer on my underwater gear, undercoating my car, calipers , primer on the hauler etc.

Eastwood has some great products that are a bit unique, and right at home on a boat.

We did something with POR15, maybe a helm? I forget what exactly but since there was some extra left on the brush I smeared it on a c-clamp that had a rough life (forgotten outside by someone who borrowed it for a year) and it has held on nicely even when banged around in the shop. Good stuff, totally not for threads or pieces that need to come apart or move. Some vasilene on those bits and seams and you should be able to cover everything and still work on it when the time comes, you wind up breaking the coating at the greased junction.

That chain wax sounds interesting though, I'll look into that for sure.

Thanks for all the replies and great information.

I have used AMSOIL MP HD with good results, it is similar to chain wax.

Also Boeing Boeshield T9 seems to be a good product but is a bit pricy, WD40 is probably just as good.
