their website is a good place to buy... It's great stuff, doesn't even compare to other products like Armorall. I use it on the dash, rubber floor, door seals, vinyl parts of the leather seats, under the hood, the bed and plastic bed rails, lots of places need it on the ST
The free sample offer is good to check out the product. well not quite free with S&H but not bad..
I've been using it for years. The CO. was very fair when I bought a gallon of it and some had leaked out during shipping. I emailed them and sent a picture of the wet shipping box and said at $50 a gal. you think you would screw the cap on a little tighter. They sent me a free gallon. I will not be out for quite some time.
