Hi there, and welcome. Forum's member, Balgrn has used Por 15 white coat with great results. I used "Tile Doctor", 2-part epoxy (which I tinted to a creamy color) and sprayed them outside. The improvement was awesome!

I remember someone using the fusion.... try using the 'advanced search'(pops down when you click on 'search'. Type in fusion paint and select your results as "Posts"- not "threads"... it makes searching A LOT easier!!
