Yep, thought it looked a bitch to sandThe products I am using are Boatcraft Pacific Australian made Bote-Cote. The filler is Bote-Cote faring powder mixed with the bote-cote epoxy resin system. I have to use 80 grit sanding belts due to its concrete like strength.
You may consider Qcells which are light and easy to sand and I have used them with great success for decades though they are getting pricier than they were but still cheaper than bote cote list for their powders
or I am looking into these Cenospheres - Fillers, Lightweight - Kirkside Products Perth WA from WA - want to be my guinea pig?
I imagine they would cost a fraction of what Bote coat and Qcell are charging for their powders.
