Which Compound?

[Sniffer]

I am at the early stages of a minor repair and need some advice on which product to use.

I need to add a very slight amount of something to a steel surface (it may have to adhere to aluminum too but I doubt it) and I am thinking epoxy or something along those lines.

Needs to have good adhesion, be able to be applied very thinly (this is the most important part), good strength and can be sanded / polished to the correct thickness.

I have not used any of these types of products but I have heard of JB weld / Devcon etc but if there is something better out there I am all ears.

Can you be more specific with regard to what materials you want to bond & to what conditions it is exposed to?

No bonding, of parts this is simply to build up a metal (probably steel but may be aluminum as I haven't seen it first hand yet) surface that has worn down a little and is causing an issue.

Wont be exposed to heat, it is hidden so colour is unimportant, needs to adhere well but doesn't need crazy amounts of mechanical strength and be applied thin.

Is this essentially just a dent filler? JB or any auto filler comes to mind!

I think it would be simpler if you just tell us what it is, you are so vague that you only gonna get vague suggestions if any !
Anyway I would suggest “all metal” bound to anything metal and can be sanded, drilled, tapped and painted

Uh, I must be thicker than a bag of hammers this morning, but "No bonding, of parts this is simply to build up a metal" implies, at least to me, that bonding WILL in fact be required!
