I just purchased and used some of the Durham's. (Form the big orange box store) $8 for a 4 pound can. It does not take much water to activate this stuff and get it to a workable paste.
Pros:
It tools beautifully
It sands easily when dry
It sets very quickly (10-15 minutes until it can be sanded)
Relatively low cost
No shrinkage that I can tell.
Con:
It SETS very quickly! Even in a sealed container!:eek: It's not like other powders where you can mix a batch, leave it in a sealed container and come back to it later. I wasted probably 1/2 pound or more.
The can does not provide detailed formula for mixing, so you have to be comfortable with mixing to desired consistency, I like a warm peanut butter consistency for spread-ability.
Advice:
Read and follow the directions and only mix what you can use in a session. This includes a dinner or lunch break. I mixed up a batch and started patching, was called in for dinner, when I came out from dinner (30 minutes?) the remaining batch in the sealed container was "Rock Hard". Fortunately it popped right out of the plastic container I was using. But was mostly waste.
Work in small batches, a scoop or 2 with a putty knife into your container with just a little bit of water 1 oz or so? at a time.
Good stuff though, glad I saw it here and picked some up.
