          Good stuff
          I like this Lanco 1-gallon crack filler the consistency of peanut butter. I used Lanco over mesh tape & Karnak 19 flashing cement after full cure. So it’s clean area then Karnak 19 than mesh tape add second coat of Karnak. Let cure 3- months then 1 coat of Lanco then paint 2-coats exterior paint . I like that you can paint over the Lanco crack filler for added protection.

            Applied the Siliconizer as instructed. Now hoping for energy savings and a more leak proof roof. Thought the stuff was on the expensive side at $89.99 for a 5 Gallons Bucket.
