Hi Everyone - I decided to take the plunge and pulled the engine out of my PK 50 to do an overhaul on it. While it’s out, I will also replace the rear shock and cables.

Today I did a deep cleaning on the frame though (it was caked with dirt/oil). You can see the paint is not in the greatest condition anymore now. Has anyone done a “treatment” to their engine bay? Now would be a great time to spray in some sort of protectant or even just a coat of paint if that would be beneficial.

Thanks for any tips you can offer!

If you wanted to, I guess? pretty much anything that sticks would be sufficient. I'd probably go with an automotive chassis or underbody paint or maybe something high heat engine/engine bay related. or even BBQ paint would work a treat.

if it were mine I'd just clean it and try to keep it clean. Looks like most of the exhaust soot is wiping away if you put undercoating it wouldn't be as easy. Paint seems to be doing a good job.

Not normally a fan of undercoating, but used this on a non-scooter project and highly recommend it. It’s a two component product. Not cheap - $35-$40 a can - but miles better than the other stuff.

Exhaust soot is a very protective coating…

I’d agree. I think that exhaust grime and oil grime is what keeps them from rusting. In other words, regular use is what keeps them alive and corrosion free.
