Cost of Rhino liner Spray On RV Roof ?

You cannot really extrapolate that way for your roof. For such a job, you'll probably be looking to use one of their industrial applicators versus the usual truck bed shop. Further, depends on the level of preparation you're willing to do yourself. You'll need a quote. At our prior home we had a concrete porch the prior owner tried to DIY stain the concrete. It was horrendous! Choices to address 300 sq ft were concrete overlay, tile, or Line-X. Concrete overlays are iffy on aged concrete without serious preparation and quality bridging products so the estimate was as bad as I expected. Tile still required so good preparation work, and my wife and I could only agree on slate so that was also spendy!!! Called up the industrial Line-X folks who shot some of the floors at the company shop and had them do a grey Aspart-X with the smaller black and gray color chips. Basically, a faux granite. Cost was $2089 and I did the prep work of protecting everything from overspray. Would have been less money if we skipped the chips.
