My friend give me this tape, he did same tape on his husky SMR510 for 1/2 year and still ok. Not sure what's it made, looks like 2mm rubber and self adhesive. Finish yesterday on my front wheel and change the D208 to Diablo supercorsa, set TP at 40psi. Check this morning, still at 40psi. Not things special! Just stick "one" layer on rim, and change tubeless valve. I'll stay at 40 psi more days, make sure the tapes stick probably on rim. Sorry, I forgot photo while work on the rim. But, the front wheel done. I'll go for rear rim.
