Has anyone used sider-proof ff-pr for resurfacing a gunite pool and if so what was your experience?

I actually used this product for my pool with great results. And used it after my neighbor had applied Sider Proof FF PR in his pool the year before.

Ok...welll it has been a year now and the Sider Proof is holding up great! I had to drain my pool and it still looks new! So far great stuff!
