Undercoating

[Joerg]

Hi,
I'm new here. Bought a 2006 FL65 recently to convert into a mobile home.
Actually cleaning/ repainting the chassis; does someone know what exactly is used by Thomas to undercoat? Frame and floor from underneath the body.

Thanks.

In preparation for installation ng my gray tank and propane, I went under the bus and did some under prep.

Basically same as I did inside.
Wire wheel
Ospho
Rusty metal primer
Flat black Rustoleum


Not an answer to your question, but I think it'll work.

No idea, but I did some grinding on the rusty spots, oshpho, then used the undercoating made by rustoleum. Turned out good.
