Can 110% agree they are coated.
Cleaned the car today, polished the wheels then thought I#d use the megs stuff on the tyres. Sat on the path and hooked my feet up under the car and spent about 40 mins carefully sorting all the tyres.
Neighbough came out and asked how Id f**ked my trainers only for me to look down and see about a 5mm coating of black cack on my trainers.
So yep, you could say there sealed! Wish you had asked this question yesterday as I wouldnt now be a pair of trainers down.
Best wishes, Neil
