Accidently put leak stopper brand patch (obviously noncompatable) on our EPDM rv roof and can't get it off. Yes, bubbling in some places. Can I use primer and the apply liquid roof or what should i do? Leak stopper is not drying/curing well but still can't get it off. Roof in bad shape before which is why my husband thought he was "helping" with leak stopper". Yes we now need marriage counseling, lol
