i find aka to be about the best for balance
in ik blue tack is very popular for balancing its putty for sticking up posters and xmas cards ect reuseable
the green dot is as said the compound but does give a good ref for rim rotation which is what i think he was on about lol
bofore i balance i stick the wheel glued on balancer and use my air line to spin the wheel round goes quicker than on the trug and allows tyre /insert to seat without getting it dirty.. wish would go that fast on my mugen lol
does anyone on here tape the inside of the tyre to stop deforming acting blike a brace to stop the piza cutter action i tried many times but tape comes off in places
the aka rubber seems to be getting popular in the uk now and proline taking a bit of a back seat
