theres a cartridge adheisive / sealant using Polyurethane... Sikkens make like most others.....always buy Sikkens where poss...........
it goes on like silicone but not as messy..I use it a lot now.....I'd fold the tyre over once mounted and then a fine beard of the POLY...
just run ur hand over the tyre to smooth it out....u dont need a big bead...
u know how the sole near the toe on ur work boots just seperates........lost count how many pairs I've binned for that reason alone.....
thought I'd try the poly...put plenty in, smeared it around with a lollipop stick and put a little weight on the toe to get it back to shape....
Still stuck on after a year.....
