FOR nogoodeco..... I spray RHINO ECO coating on RV roofs. Sounds like to me that the person spraying the eco coating was not trained by RHINO personnel. Big mistake you did on your roof was to seal all your seams with fiberglass sealers. Fiberglass will crack when you walk across those areas on the roof. We use SIKAFLEX 1A which is construction adhesive and is pliable which makes a good seam sealer. The pinholes should have been caught by the company the sprayed your RV. A good sprayer will check his work before he lets his product leave his facility. The warranty is only offered by the facility that applied the eco coating. RHINO warranties their product if it was used properly. RHINO will not sell me there product unless I have been trained by them first. Sorry to hear that you had a bad experience with the company that sprayed the eco coating on your roof. eco coating if applied properly will outlast your RV.
