Hello Sharman, thanks for reaching out. We don't have that exact SikaFlex 715 sealant in black, but we do have something very similar. Take a look at the following:

- Alpha Systems 1021 Self-Leveling Sealant for RVs - Black - 10.3 oz - Qty 1 # AL48KV

This is a black self-leveling roof sealant that will adhere to any metal, rubber or fiberglass roof. It'll be a great alternative for the SikaFlex 715 and costs a good bit less too.

Any cool trips planned once you get the roof sealed up? Camping season is almost here!

I also used the Alph sys 1021 self leveling sealant on our Winnebago motorhome where I replaced a bathroom vent. It works great, I’ve had no issues with the area I sealed with this product.
