Does Anyone Know about this Stuff?

[Dallas]

I have been doing some RV roof repairs and normally use Dicor White 502-LSW Lap Sealant.
While it works well, my supplier asked me to try some stuff that a salesman gave him to sample.
This stuff is TremPro 638 SSL semi-self leveling Lap Sealant.
I went to their website, but it didn't tell me a whole lot.
I was just wondering if anyone has any experience with this product.
Other than being gray instead of white, it has a good feel to it, and seems to have a smoother finish than the Dicor.
Any help will be appreciated!

Dallas,

This stuff looks just like the tubes that came with a walk in box we put together not long ago!

I will have to try and confirm that. Anyhow the stuff was very smooth like you discribe and it worked very well.

I remember it being urethane based.

I used trempro 650 it is white, I used it to seal just about every seam on my conversion it is easy to work with smooths out and best of all paintable.
