Im really impressed I sanded the hell out of my box first, the kit had more than enough for a 6 foot box. Its been in about 6 months and held up as good as my factory bed I had in my last truck. Ive dragged skids out of it and hauled paving stones its held up fantastic. That said I didn't realize I bought the tintable, when I opened and found white with my truck already prepped. I used cement dye to tint the product and it worked great.
