Seal membrane inside bucket only contacted product on 2inches diameter out of 4 5/8” diameter bucket. Made about 10-20% of bucket unusable because it had hardened into an inch plus thick donut. Tried to patch a crack in wet tar on roof and paste wouldn’t stick just rolled up onto other side of putty knife. Worked good on A/C hole in window.

Don’t Get What You Pay For
Would RecommendThis is a great product..... however, only 3 Stars because I expect to get what I pay for! I purchased the 6 lb. tub, so I expected to get 6 lbs of usable product.

This not the first time either. I have purchased a total of three of the 6 lb. tubs and three 1 lb. sizes over the last two years and ALL of the...
