There is the Allison shop at 19ave, just south of I-17. That were I get my filters. Good guys, friendly and seem to know their stuff. As for aftermarket, I am not sure.
Liquid Glass for me. It gives the truck a mirror like finish, easy to apply and last a long time. I put three coats on a new car and re-apply once a year. I also do the windshield so the bug guts don't stick.
The fun part is to put it on a small area of a friends car and have them put a beer...
I was just getting my post count up on another site and now I've got somewhere else to spend my day. I do see alot of names that I've seen before. I know the info can be found here. Hope this is an E ticket ride!
