Howdy.. I'm looking for help here.. I need to address some patches of surface rust on the bottom side of my truck. I've got the body off and on blocks and am ready to go to town.
But, the factory undercoating is showing itself to be SUPER resilient. I don't expect this to be an easy job, but whatever I can do to make it better would be great. So far I've really only tested a wire wheel on a grinder.. That will get it off but it's super messy and only really good for flat sections. It isn't gonna work for any crevices, etc..
Has anyone got experience here? I've heard of people heating it up and scraping it off (I'll try that this weekend). Perhaps chemical stripper? Or sand blasting (seems like it will just bounce off)...
There isn't any rot except one spot on the front of one of the rear wheel wells, but all the seam sealer is cracking. I'd like to get it down to bare metal, put on an epoxy primer, then a coat of lizard skin or similar.. Then I'll fluid film everything once it's all back together.
Here's what I'm working with:
