Rated 1.0 out of 5.0 by Tim GAF let me down !
This product did not stick to plywood. Very hard to work with. Left sit for two days and came back to bubbles and wrinkles. 85 degree day so it should have stuck. It does stick to itself real good. GAF needs to look at this and correct the problem. It was installed over new plywood. I hope the GAF shingles and starter shingles don't fail also. They advertise you need to use three of there products to get the lifetime warranty They need to do better on this product. I should have read the reviews before I purchased this product. They all say the same thing.

Does not stick to plywood! I know that sounds odd, it being an underlayment peel and stick product. But it is true. What were they thinking when they put this out.

Rated 5.0 out of 5.0 by MANINBUFF STORMGUARD, ITS STUCK TO MY HAND
Stormguard is a pain to use, until u start to think about what it is and how it works, so i used it to my advantage, first its heavy, so i cut it on the ground, (instead of on the roof), second it seals around the nails and if you read the install sheets it should be cap nailed down, so to stop it from sliding off the roof i would put a couple of nails in the top 3 inches to hold until i can get the white paper film of off the bottom half and stick it down,pull the nail at the top, peal the paper and your done, then just nail the rest down,
The only down side i can think of at this point is that the white film paper on the back is so hard to cut, but i fixed that problem too, just put if face down and cut the back side first, seems to work for me,
By the time i am done with my roof, i will have used 13 rolls of the stuff, i have used 4 as of today, i'm working alone on a 33 square roof that is my summer project, i will review every GAF product is have used under the maininbuff heading

Very hard to work with on a steep slope. Release liner constantly rips. Does not stick well to new plywood. Roll telescopes and slides down the slope. I've done half my roof so far and I'm thinking of taking the rest back for another brand. I originally ordered the Grace but the Metal manufacturer said the nail buttons would show thru the metal.
