Chassis Cleaning & Undercoat Project
Been working on the "Munch's" underbelly last couple weekends. I just couldn't stand to look at it anymore like it was. Not that there is any rust, it is just dirty and needed some attention and a few new bushings.
Armed with a scraper, a wire brush on a power drill, a can of easy off oven cleaner, and a pile of rags, my progress is slow but sure.

Re: Chassis Cleaning & Undercoat Project
I am using a rust preventative primer and then a couple coats of satin black rust preventative paint. (Nothing high dollar - just wanting it clean and thick.)
I was looking into using "Herculiner", but decided against that. I know it would have worked ok and been durable, but I don't want bolts and screws coated with stuff where I can't put a wrench on them if I need to take something apart.
Something else I was considering is that fact that this is just a weekend toy. I am not driving it as a daily driver or in bad weather. So this is where I decided to go with it. But on the other hand, this is not really a show car either - so I wasn't about to disassemble the car and put it on a rotiserrie to bead blast it and shoot it perfectly with a high dollar paint coating.
Also, I am afraid powder coating is not a very good way to go on some parts - to "bake" the powder coating on, they use temperatures of around 500 degrees and that is approaching a point that can change the properties in something like a sway bar or the pan hard arm, etc. To "draw" a temper out of steel, it only takes 600 degrees and you never know when someone is working on your stuff exactly what procedures they are following. They could have a new guy in who turns the oven up too much.
However, the smaller parts like u-bolt shackles, heat sheilds, exhaust mounts, etc. I am sand blasting. I am painting those with an etching primer and then hitting them a few times with the ole rattle-can.
So this was the route I decided to go with. I think it is by far an improvement!!
