Excellent product!
Very sticky, no need to worry about delamination. I'm not one for being on a roof, so the nonslip surface was just what the doctor ordered.

BEST product for WIP Bar None!

This product has no true equal. With its ease of use and application and its extreme performance nothing works on this level. I have used this product exclusively for the past 10 years
Out here in Northern California I have seen how well this product holds up even in wild fire conditions.

I do test and tryout other WIP products to stay current, but as of this writing I have not found anything close to SHARKSKIN ULTRA SA.

strong durable underlayment

looked at video of shakskin ultra sa and had 2 men pulling on 2 pieces that were stuck together didn't think the adhesive would be that strong, so I put a strip approx 3 inches wide and a foot long over a scaffold board with about 1/2 hanging over the edge and attached another piece about the same size had the adhesive side on one attached to the printed side of the other with approx 5 inch overlap and could hang from the end of the second piece, I am only 160 lbs but I have done this several times and it still holds together. We had over 2 inches of rain with 20+ mph wind gust yesterday and no leaks and still looks the same as then I installed it 2 days prior to the rain. Ordered underlayment on sunday afternoon and had it delivered to house on wednesday at 5:30.
thanks craig
