Non-residue, low friction tyre fitting gel. It does what it says on the pot!It leaves the tyres cleaner than traditional tyre fitting soap (paste). We have used both in our workshops and whilst the gel saves a little bit of wiping, 250ml of gel is the same price as 1kg of paste - how much do you hate cleaning? On balance the gel is marginally easier to use, but it really comes down to preference. In a busy tyre shop the soap wins hands down on price.<<
