Rust coating removal

[pflaming]

I am in the process of cleaning out the engine compartment. The firewall cleaned nicely. the inside fender wells are covered with a 'tar' treatment, probably an anti-rust coating. Do most people treat for rust from the bottom and paint the top? Seems that way from pictures I am looking at.

Took a longer look at the fender wells after the cleaning I have done. It appears they are removeable!! If so then they could be sandblasted and painted outside the truck. Am I correct on that observation?

Yes they do unbolt

Was informed this morning that the coating on the inner fender covers is for VIABRATION reduction NOT rust protection. It is the same material that is sprayed inside the doors for the same reason. I was told that if I removed that coating, I would hear a strong "hum" caused by the viabration.

Question: Is this correct and if so how is the road 'hum' controlled if the coating is removed?

If you want to clean them up and prime them you can then topcoat with any type of rust preventative color you want, and then use a rubberized undercoating on top of that for noise. My inner and outer fenders are just painted. Used a primer for rusted metal after cleaning them up and welding in the patch panels. I then used a paintable seam sealer on the joints, and topcoated with a black rustoleum. This doesn't see much rain, and is never in the snow or salt. There are so many other sources for noises. As long as they'be bolted in properly I wouldn't imagine they'd make much noise. Mike

Mike, thank you. I am doing an off frame rebuild, way beyond my ability. So I am going to continue with the steel brush then recover in some way for protection and better appearance. Is the stuff they put on truck beds a possibility.

This is a pic test on my 52 pickup.

PF-I think you're going to have to be almost bare metal clean if you want the bed liner material to stick to a primered surface. I tend to operate on the KISS principle (Keep it simple stupid) and have to remind myself periodically to stick to that. I like the rustoleum as I can keep an eye on what is going on if I get a stone chip underneath, and its an easy touchup if I need to make one. Whatever you decide to use, cleanliness and preparation are the keys. Make sure you wear a respirator while you're doing the wire brush trick-who knows what lurks in that dust. Mike

I miswrote earlier, I am NOT doing a frame up, I'm just going for a nicely cleaned up truck so "keeping it simple soldier" is what I want. I will leave whatever amount of original coating that stays and then do some sort of over cover. Will the Rust-o-leum stick to that old material? If so, that will be my choice. Paul

I removed the coating from my trucks panels by softening with kerosene, allow to penetrate and scrape off. The areas I didn't remove were painted over after cleaning off the dirt and other residue. The paint is still there ten years late.
