I got mine at Napa I've seen it at Walmart also. Most boat supply store should have it also. Looks like the waterproofer might be for fabric though. You'll have to check into it. Good stuff
Picked up a set of American Outlaw mirrors. Now I can see when I take the doors off
Also got their rear window straps. My stock ones were getting a bit stretchy.
I use the 303 FAbric/vinyl cleaner the follow it up with the water repellent. Works great for me. I have the premium soft top. I just use an old boot brush that was never used
