Customer –
It’s no good without a nozzle!!!! Received two tubes, both without nozzle.
Camping Queen –
We needed to fix the fractured sealant on our new Imagine. We purchased it at the end of the season and although it took a while for the product to arrive I applied it the same day. The Canadian climate didn’t want to wait for optimal temperatures so I applied it while it was as warm as it could be at 7C. I left the tube inside for a few hours and to my amazement it was very easy to apply. I have checked it since and it has adhered very well. I was impressed.I would recommend this product.

I ordered one tube of this sealant. It arrived without the accompanying nozzle — necessary to product application and clearly shown on the product photograph. So I returned that one. And the replacement IS ALSO MISSING the nozzle. Seriously???
