The OP is to be congratulated in getting some seal, but I can't see how this tire works with the "fiber sealant". Perhaps a latex sealant where the rubber micelles coalesce and form the seal part of the rim are what is called for? Does the tire mfr have a recommendation (OP: I'd check in with them and give them the link to your post. I suspect you'll get a very fast response).

Just as a question, what is the percent sealant (fiber or latex micelles) in each sealant? Is Finish Line as clear as the stuff seeping out of the tire?



If liquid is seeping through the membrane, then gas can seep through it. So I have to agree: this seems like a very poor sealant for the application. The big pores and grooves of the fabric where the tire seats in the rim needs more large-pore sealing capacity than is furnished by the Finish Line non-latex fiber-based sealant.
