Mr Bell STONE COATING & WINDOWSILL STONE COATING

I used this product back in summer last year, I was doubtful at first as to whether or not it would do what the website says, as I began to coat my sills I was still doubtful. Then coat after coat (2-3 Coats) the product built up and started to look fantastic, my sills now look like brand new and I am so grateful that this product is available. NO MORE DIRTY LOOKING SILLS!!! Fab Product Thank You
