I did that with my Cecropias. Works VERY well.

I actually rolled it on using a foam smooth roller. 3 coats, 10 min between coats with a fan on it the whole time. 30 mins later sanded with 180 grit just until I started to burn through. Then rolled 2 more coats 30 mins later quick 220 grit then quick 320 grit then blew it off and painted rattle can orange.
my duratex has always hardened.... takes a couple of days maybe to fully harden. Good to touch in a hour or so, and can be re-coated. But wait at least a day to sand - it may feel hard to the touch in a couple of hours, but it's not fully cured... a day or preferably two before sanding is good. I am not sure about sticking, but then then you can use small furniture felt pad - i always use that...but it definitely hardens....
Have you tested it as filler/primer over a MDF butt joint?
Hi Brad, So, if I am reading this correctly, you would not recommend using duratex as the filler/primer for something like my Dr. Diffraction donuts. When the weather improves, my plan is to sand them perfectly smooth down to about 220 grit with my hand sanding templates and then make special matched radius applicator templates to skim coat them with bondo. Then sand smooth, then re-bondo, etc., etc. Bill.
