Commercial roofing suppliers sell patch kits for EPDM roofing. RV
dealers also have sealant for EPDM roofs on motorhomes and trailers.
Both these products will make a permanent repair. If you do use RTV
sealant allow extra time for curing. Until it is completely cured RTV
gives off ammonia.

I need to repair some leaks in our EPDM 45 mil rubber liner. Already
tried
the single side seam tape. Did this when it was cold and it did not
stick.

I would love to know what could be directly applied to the rubber.
Would
stick tenaciously and would be 100% water immersable.
