I needed some epoxy filler for my model sailboat so I decided to give this stuff a try and so far so good. I used a small scale to measure out equal amounts and mixed it with doubled up craft sticks as this epoxy is quite thick, so it really worked well for adding vertical fillets without any sagging. It does however have a low enough viscosity to use a disposable sandwich bag with the corner snipped off as a piping bag to apply an even amount right where you need it. It cures very hard with a joint that's stronger than the surrounding wood (I did a few test pieces). It sands easily with 80 grit and has a slightly off-white color after sanding, make sure to have some form of dust collection as the particles are very fine and float everywhere, probably don't want to be breathing that. It's also alcohol soluble so cleanup is easy with some isopropyl which is nice since it's like peanut butter and sticks to everything it touches. Quick tip: if you need to smooth down a fillet or whatever you use it on, wait about 15-20 mins for the epoxy to set up a bit, wet your (preferably gloved) finger with some alcohol and gently smooth it down for a really nice finish with minimal sanding. Fiberglass with regular old epoxy also bonds very well to the filler so yeah, really good stuff with nothing bad to say about it, I'll definitely be buying more when I need it.
