Hi Harold,

Where did you find the 70F or more part? I was told otherwise by my TT manufacture when I had to change a roof vent under warranty during the winter.

I found this on the Dicor site, just no temperature:

And then under installation it states this. The tube I just checked in the basement says the same thing

Directions for Use:
Clean surface of all dirt, loose paint, rust, oil and grease. Allow surface to dry before applying sealant. Use standard caulking equipment to apply sealant. In cold weather, warm container at room temperature before use.

While I agree, if there is a heated building option, take it. In my case that was not an option. I had a bad roof vent on a new camper that rusted big time prematurely. The factory sent me new vents, butyl tape and Dicro. When the products came I read the tube and it said nothing on it about temperature. So I called my TT factory. They told me to keep the products inside the house (room temperature) until they were ready to go on. And that it be at least above freezing outside. They needed the old parts back within 30 days and had no issues with the way I told them I had to install.

I followed what they told me and the repair came out acceptable. The self leveling is a little less then when I use it in the summer, however I have no found ill effects since. It was 40F out when I did this. And this was a warranty situation.

See here.




The new one installed. And this was in Ohio in 2005 and is still OK


Even in the spring time when it is only 65 etc it works well.

Help show us where you found this so we can get this straightened out.

Thanks

John
