Hi!
I'm building a little pop-up teardropp-ey type of thing (it's sort of like a mini Cricket).
The floor of the trailer is made out of some 1" aluminum honeycomb panel, the bottom of which is exposed directly to the underside of the trailer. It's awesome stuff, very strong, but I'd kind of like apply some kind of coating to the bottom of the trailer just to maybe help corrosion & dings in the honeycomb panel (the panel skins are pretty thin @ .022").
I'm thinking about applying some truck bed liner - either herculiner or the rustoleum spray-on stuff (which by all accounts is a lot thinner, but it's also cheaper so..)
Anyone have any experience with either - especially in the context of coating a trailer bottom? What other coatings should I consider (that can be applied directly to metal)?
Side note: this honeycomb aluminum panel is awesome. A 5x10 sheet weighs something like 35 or 40 lb, has almost no flex at all. I got an awesome deal on it - bought it surplus from Palmer Johnson yachts in sturgeon bay, WI.
Thanks!
