I’ve been using System Three’s SculpWood for repairing rotted window sills, door bottom’s and exterior plaster (the correct name escapes me) for about a year. I know others use West System and the only reason I probably stay with this is that it requires no added mixtures. I usually mix up some Rot Fix which is just a two part liquid epoxy first and then use the SculpWood once the first has set up. I have used West System 105 with a hardener before I got the Rot Fix and I see no difference between the two. My biggest complaint is that I have difficulty getting the 2 quart size of SW and have only ordered it direct.
Is anyone else using this or a similar product? Bondo has not worked as well long term for me.

If your Bondo is setting too fast,I use white hardener paste,it's slower and works good in the southern summer heat, I usually try to build up a little high and when the mix starts to harden,I get my razor out and shape corners,and pop off any little dams I've built to form the profiles...the only draw back to this is the color is no longer a good indication of when you have a well mixed batch...
Scribe once, cut once!
SculpWood gives me a good thirty minutes even above 90. The bondo was turned loose after a year...and even when a guy that repairs cars did it, the same thing happened. Of course, the T-111 was delaminating anyway.
Sounds like I'll wanna try Sculping ,I only fill in solid materials and use some screws into something solid as an anchor, Sounds like all or enough of the rot isn't getting removed from the work where the bondo was used and popped free...Scribe once, cut once!
On the door I just finished repairing, there wasn't enough sound wood to put a screw into. I wanted to replace the bottom of the door but that double pane was very big and heavy. One side of the door was fine so I chose this method. I explained to the HO ahead of time and got their agreement (not in writing) to do it this way. I have to go over in a few hours and sand it and look for any little pinholes, etc. that I might have missed. The stuff is expensive but I charge for it...just wish I could get it local.
I'll try my hand at posting tonight (a picture) (if the repairs look good enough.

I just reread your post. The bondo that popped was used to repair (try anyway) T111...but I also tried it on deep rot and just decided it was better to use epoxy...I may try the longer open time hardener you mentiioned though.
