Seriously though, I guess it happens to all of us, sooner or later - but, Jimmy, what about taking pictures of your existing builds? Again, I'd love to post anything(s) you send me, and/or help you to post 'em directly.
Meantime, your specific mention of painting made me realize just how much I've been "automating" this operation - that is, masking and spraypainting - as an alternative to brush-work. And not with a demanding airbrush, either, but with rattle cans and (if you can believe it) even simpler ways of spraying paint.
Only the masking part demands dexterity - but here, since it's prior to any painting, it is completely forgiving; allowing you as much time - and as many do-overs - as you may need.
Jimmy, if you want to take a crack at fixing the paint job on your Hawaiian Pilot (of which I, too, have a an available demonstrator on hand), I'd be happy to take you through my best techniques - step-by-step - on it, buddy. Or on any other build, for that matter. It would be a lot of fun - and, I think, also highly likely to produce yet another new trick or two, in the process. What do you think, man? (Is your SeaBulk offshore oil services tug model already built? I'd love to see it, either way!)
Just let me know - about any of the above - and THANKS for all your sharing with us, buddy!
Meantime - and this goes for everybody out there: Never stop lurking ModelFleet!
