Hey, for you tires I have a great idea.
Alsa Corporation "Rubber Paint"
Nothing sticks better to rubber!
Rubber Paint goes where other paints dare not tread! It sticks to most rubbers and pliable urethane substrates with unequaled "stretch". No more cracking or peeling like traditional paint. Our special formulation retains it's flexibility much longer than other products which use flex additives that leach out of the paint finish over time. Rubber Paint is an ideal product for restoring or retouching the color if your rubber.
