Get some Anglewax H2GO it’s probably the best windscreen sealant I’ve used if you don’t want to go full ceramic.
Another fan of AngelWax Bilberry Wheel Sealant here. I grabbed a few bits in The Piston Works sale (and got a free HotWheels car!!) yesterday.
I bought my Michelin from Camskill and had them delivered straight to Lepsons whilst having the wheels refurbed, both companies were happy to let me do that and I saved on tyre fitting costs.
Thats a thumbs up for both Camskill and Lepsons both really pleasant to deal with and helpful.
