i have been using WG sealant for about 8 months now, although i am satisfied with the ease of use and the finished look, i am disappointed in the durability. i am almost out and need more sealant and am considering UPP or EX-P. does anyone use either one of these products that have also used the WG? if so, how does the EX and UPP compare to WG? My ultimate goal here is protection and durability, im going to use #16 as a topper.
