This is quite a useful filler. Mix a little powder & you can run it into fine cracks. Mix a lot of powder & it’s like a gel to fill a large hole. The only criticism is it was still a little sticky the next day which made the sandpaper clog up.
It doesn’t smell like aradite though! It smells like fibreglass resin!
As a filler, it's fine. I was surprised how little 94g goes. I bought a much bigger tin from screwfix to finish my (not massive) job with loads to spare.
