thanks guys for the feed back.
 
Dennis , thats unbelivable, looks like a faliure in the top coating, the hydrophobic.
 
Sure i'll stay away and with due respect to opinions on testing before applying, how long will you test?
6 month or at the most a year, so what! problems can start to appear after that then you're stuck with a bunch

Actually i decided to go with an american made brand, maybe more expensive but for sure backed up.
 
thanks again guys
