Plastic cements will not work at all (solvent types) or very poorly (tube types) on resin parts. Use CA type glues or epoxy as mentioned above. Be sure to wash the parts, as some casters use mold release that will cause poor paint adhesion. Auto Body putties stick well to resin if you need to fill a gap. Cut off as much excess casting sprue with a saw (if there is an excess). Wet sanding will keep the dust down and make the cats happier - or at least as happy as cats get. Resin is very soft and can be sanded or cut very quickly and with little effort.
If the part is to be attached to a plastic model, it never hurts to pin it with brass rod instead of relying solely on the holdin power of the glue.
Prime the parts with a quality primer, such as Floquil, then overcoat with the paint system of your choice.
try a detail set like a cockpit set first, then move to other things like resin cockpit canopys, resin updates/corrections, then scratchbuild your own! ← jk
I always use CA glues for working with resin and have had great results with it. Use one that’s a slower curing otherwise once they’re stuck, they’re good and stuck. There are some concerns with resin dusts and health. Just keep the little furballs out of the room while you’re working with resin and clean up good behind yourself and you should have many unhappy years ahead of you with them. LOL
Gary, here’s a bit more info that some people may not know. Resin dust can be toxic, especially if burnt, so don’t drop it into the ashtray, it can produce phosgene gas, highly naughty. As above, I’d go for the wet sanding, using plenty of water, and superglue or epoxy to fix it in place.
P.S. Cat whiskers can make great whip aerials!
