Posting here while I wait for the Gunpla General as you guys would also be relevant. Sorry that this does technically go in the gunpla general but people here would know about the putty.
I'm stumped on part of a build. I am trying to show the cockpit I'm adding to this Mock, but I want to cover portions of it so it only shows the important mechanical elements, which I highlighted in the photo. I tried using Aves epoxy putty by attaching it to the edges and sanding it to the right shape but I'm guessing it doesn't grip/harden correctly because while sanding it always cracks. This is even though I've been told it should cure rock hard, and have tested some consistencies with the same result. I have plastic sheets too, but then they would need to bend. I intend to glue the clear green over the details so it shows through while not being exposed, sort of like a plane canopy.
Do I have to glue the epoxy putty to where it is staying? I feel there's some element I might get eventually, but maybe someone else here already knows that I'm screwing up somehow.
If anyone has a guide on using Aves epoxy I would greatly appreciate. Any time I build onto something I always end up crumbling the epoxy while sanding, unless it's going into a large cavity. I don't intend to make a downward cavity here, only a side to side cover which doesn't ever hold. Glue was what came to mind, but if I'm dumb for not making a beneath layer like a skeleton for the epoxy to go on then by all means point it out to me.
