Btw, this stuff isn't exactly cheap (one pad is the same price as a bottle of Back to Black, about $6), but IMHO it's cheap enough to seriously consider putting it on as frequently as once a month during the summer to keep it nice and dark. Figure $40 including shipping for a 6 pad supply, 2 pads per application, maybe a total of 6 applications per year = $80 a year for amazing looking cladding. If you stick with the every 3 months model you're at about $53 per year.

There's something to be said for the fact that after awhile you could have just bought GatorBack for the same price. But this is certainly something to consider if you're wary of permanent treatments.
