Is Eternabond okay to use on this type of roof? Thanks for your help.
Eternabond is safe to use on your TPO (thermoplastic polyolefin) roof. TPO is good material that requires little maintenance beyond visual inspections from time to time. Lots of info regarding maintenance if you look beyond the use as an RV roofing material and more with commercial applications which is where probably 95% of the TPO made ends up.
Regarding sealants I've replace 95% of the liquid based sealant on my roof with Eternabond tape and in the few areas that tape wasn't ideal I used EternaCaulk or Microsealant. The service life of all three is in excess of the 15 year warranty, they are safe for TPO and EPDM roofs and will probably outlast the coach under it.
Dicor sealants? All I can say is Dicor sealants are not your friend and will fail without warning causing a leak and the associated RV cancer that water damage is.
