Seam tape

It only good for flat surface if there is few small bumps it will not glue with the bumpy profile it will pull away from the rubber next few dsys

Hey Andrew,
The Seam Tape should conform to small bumps, but If it didn't bond then there may be some type of contamination on the surface or an existing product like silicone. The Seam Tape will not bond to silicone.
