One of my many sayings has always been, "Friends don't let friends have shiny tires." If you agree with this very important philosophical existence, then you want Perl.
This is the original product that turned me onto CarPro. Perl is not one of those remarkable products that blows your mind with some fancy science. It's just tire dressing. But it's tire dressing that works and works really well.
Clean the tires with Adam's Tire & Rubber Cleaner
Apply even layer using Adam's Foam Block
Wipe off excess 5 or 10 minutes later
You can use this on any type of rubber, trim, engine bay, etc. I only use it on the tires, and I use it straight out of the bottle at 1:1.
