What is the sticky wax on frame?

[Leon00000]

Hello everyone! I just notice some scratch on frame wax (that sticky thing), probable happened during jack it. Looking to touch up but i called some dealers, and they said it is a spray undercoating, but no longer for sale. Any recommendation for undercoating? I live in Toronto, Canada. Winter is crazy here, i don't want it rust too early.
thank you!

anything your local auto parts store sells thats called an undercoating. the factory under coating is easily scratched and unless your going to recoat the whole underside with a second layer it won't really matter much. just driving along with some of the debris still on the road from ice and snow is probably scratching it in places you haven't even noticed.

Not all undercoating is good. The rubberized crap traps moisture and is shown in lots of real world evaluations to be potentially harmful.
Fluid Film or WoolWax are two readily available to the consumer coatings that are waxy oils somewhat like you have. Oils and wax treatments are self healing also, they’ll warm up and flow to recover a scratched off bit.

Look up Cosmoline....its all you need to know about this subject....

Cosmoline is the absolute best product to apply in the critical areas of the underbody. As it heats up in the Summer, it literally applies itself again by slowing melting into areas that were missed.

Very common and very effective for old skool Armed forces to keep corrosion off weapons in storage or shipped overseas. Good product for up North.

I had all my factory undercoating removed and had a place redo it with their stuff. Much better.

Another vote for Cosmoline.

woops that was a 2015, didn't know I was in 2021+(wish I was though, haha)

LPS-3 another waxy type, good for spot or replacement parts. I never found a good source for Cosmolene.

Best match I found is Daubert Chemical NOX-Rust X-121B.

On my 2016 it was a perfect match. On the 2021 the shade is off a little, but still seems to match the general characteristics of the factory undercoat. I like it is available in a spray can. Info can be found here.

Otherwise, for bare metal machined parts or others, I like Amsoil MP-HD.

Both are wax-like and flow, self heal, and protect associated parts. The Daubert is black, the Amsoil is brownish.
