So my build is really slow. (full time job, weather etc) I am at the bottom finally and was going to order the Bright Side paint for it but the young lady at CLC said they were using automotive undercoating now in the classes. Specifically Rust-Oleum Undercarrige Black 1 quart can. However I can only find it on line but don’t seem to be able to actually buy it! Checked the Rust-Oleum site and can only find mentions of Truckbed Liner. It makes sense that a undercarriage paint would be great for wear and tear if I could find it! Any thoughts on weather “ Undercarriage and Truckbed Liner are the same thing”?
We put it directly on the epoxy. I can tell you… Do *NOT* use this stuff without ventilation and VOC canisters. It took overnight to dry before we could flip it back over. Once home, we still had to do several fill-coats of epoxy on top, which still seems to adhere well over-top the the black liner coat. (Varnish as well.)
We covered the bottom with the normal epoxy/glass coating as per instructions. Then we sanded it with 80 grit to make it a bit rough. We put marine deck coating on it after that. Ends up a hard grey/black shell. We went up the side about an inch to protect from road kick-up.
