FWIW, there is a "use it all you want" 30% off at Advance AP that'll get it down to $11-ish. I got it last week but haven't had a chance to try it out yet on any of CarMomma's or CarBoy's tires. I did put a layer of the TW Jet Black Trim Coating on her left running board for testing and so far, so good. Her *MAIN GOAL* is that it not provide any extra 'slip' as she actually uses the step to get into and out of her Denali. Asked her the next day and she gave it the thumbs up. :dblthumb2:
Back to the OP;
Megs Hyper Dressing may indeed be your most cost effective solution. I don't like it though as unless you do lots of wiping, (and then don't drive till it's dry) it'll sling.
I'd look more into gels.
Really like Opti-Bond and the in-house brands from AG. If for no other reason.... that they don't sling.
Want something that'll shine like crazy for production work? Call Zep!

CarMomma works at a car auction and they used to (when I was still driving a tow truck) buy an aerosol Zep product, multiple cases at a time. I can assure you however that it's LOADED with silicone! (As are quite a few tire shines to this day.)

Not what I'd put on my own vehicles, but it sure worked for them on the "running and driving" cars.
