I have to build up the door frame over which the McMaster door seal will fit. I have to add thickness at places as well as build some extra length (Max 1/4 inch). Will Cab-O-Sil mixed with micro be strong enough, or should I use flox in place of Micro?
Thanks.

I have purchased the McMaster-Carr seal and will have to modify and add material to make a full 1/4" thick mounting edge for the seal.
I used the cab-o-sil and epoxy to glue the two door halves together as directed.
Anyway, when I see the word "flox" used, I thought it was the epoxy/cab-o-sil mixture. So what is flox and where do I get it?
If you want to see the difference mix up a ball of epoxy with micro and cabosil and then make one with flox and cabosil. You can sand the micro ball but the flox ball will be like a rock.
I talked with Don from the West Systems people a few days ago. He told me cabosil (their 406 product) is good to build up a vertical surface and for my needs, up to 3/8 tall, should require no supporting cloth on the sides. Then to fill in gaps use microspheres ( their product 407) as it is easier to sand. No need to mix 406 and 407; use one or the other depending on the intent. They saw no need to use flox or microfibers (their product 403). They refer to this as a wetting product, good for adhering structures to wood.
One thing I was made aware of when building is some of the WS products,particularly 407 I believe, is not recommended in areas where heat could impact its cured state due to sun. Example on tarmac with sun on dark paint.
