Post a close-up photo for us to inspect.

Personally, I wouldn't use rubber rim-strips on anything over 25-30psi. I've tried all sorts of things: strapping/packing tape, multiple layers of first-aid/hockey tape, electrical tape, masking, duct tape, multiple inner tube rim-strips, etc. Given the low cost of Velox versus the dollars I would be earning if I wasn't messing with trial&error experiments with home-made rim-strips , I'll only use Velox from now on as my time is way, way more valuable.

BTW, the secret to Velox is the fabric's thickness and stiffness. The glue that stays tacky is also part of its success.
