    Pro grade RTV

    Since I have only been using this for 2 days now I'll give it 4 stars, a month from now I could give it 5. The shipping was fast and the product seems to be very good. It has just the right firmness to hold without sagging and it works very easily. I will be ordering another 100 tubes in a couple of months.
