They seems to deliver all over the world.
It is a color which resembles a foam, and which once dry resembles rubber. It resists the "high" temperatures, is elastic, thus does not crack, does not attack rubber and is of course matte.
Before applying it: to clean the tires with acetone while rubbing with the green side of a sponge Brite Scotch tape. After drying, to start again with detergent Saint Marc diluted in hot water then to rinse.
To let dry approximately 2 hours and paint 2 or 3 layers.Not to be worried to put color on the rim, it is enough to wipe it with a rag, by putting its nail between the tire and the rim as guide.
