I’m getting ready to clean and paint the various frame cavities like the inner fenders and suspension pan.
I’ve ran a bore scope through them, and they look pretty decent, albeit rather dirty. The inside of the front suspension pan seems to be decent, though there might be some surface rust, but it’s hard to tell with the bore scope. It looks like most of the cavities are painted with a black primer.
Let me know what you think of my plan:
I’ve got the whole front disassembled now, and I’ve pried open one of the access flaps to the suspension pan.
1) clean the insides of all the cavities with POR15 Cleaner & Degreaser. This looks like an organic solvent combined with a base and some surfactants. Seems like it would make an excellent cleaner with no residue. I’ll be spraying with an undercoat gun and wand extension, letting it sit moist then rinsing with water.
2) spray with EvapoRust to make sure any rust is gone, and keep the EvapoRust moist by reapplying it every so often. Water rinse.
3) clean again with POR15 metal prep. This is a phosphoric acid based phosphating solution that should remove any remaining rust, and leave a layer of zinc phosphate covering everything. I don’t think it will harm the existing black primer. Water rinse.
4) spray with Eastwood interior chassis paint. This is a very low surface tension paint that also has a phosphoric acid based etcher, and is designed to creep into every little crack and seam, and designed to seal any existing rust.
Yes, I know I still have some more prep to do, and I’m going to hit the sloppy MIG welds with a TIG to smooth them out.
