HENG'S Industries Rubber Roof Coating, 1 Gallon, EPDM, RV Motorhome Camper (42128-4)

- 1 gallon rubber roof coating
- Made for RV EPDM roofs
- UV resistant, non-toxic
Our take
Hand it to a weekend owner resealing a few worn seams and the area around the roof air conditioner.
Why it made the shortlist
Heng's puts EPDM right in the listing title and describes the coating as made for use over RV rubber roofs, at seams and tears, and to seal around vents and air conditioners. No other pick states its purpose this plainly, and it matches the job most owners are trying to do on an aging rubber membrane.
The coating is UV resistant, expands and contracts with the roof and resists cracking and impact, in a non-polluting, non-toxic formula sold as a one gallon pail. Heng's is the highest-priced gallon here, and the extra outlay pays for a product aimed squarely at rubber roofs rather than a general-purpose coating. Lined up against the Tenee, it trades the stretchier reflective film for a formula aimed at rubber roofs, which buys a direct match to the roof type most owners have.
A single gallon goes a long way on spot work, and the part-number listing makes it easy to find again when the next touch-up season comes around. A weekend owner with a classic rubber roof, resealing seams around the vents and the roof air conditioner, is the exact buyer.
What works
- EPDM is named right in the product title
- Meant for seams, tears and vent areas
- Flexes with the roof as it expands
- Non-polluting, non-toxic formula
Watch out for
- Listing gives little coverage detail
