Definitely a more difficult decision. Many built kits don't have a lot of resale value, even if built very well. I have considered just giving them away to family and friends before passing on...
Also, I don't know about "burdening" my kids with my models - they might feel obligated to keep them even if I wouldn't be offended if they got rid of them.
If you have a big collection, sell them all now or anytime before you die. Then put all that money in a savings account. If you want, pretend eBay is YOUR personal stash, only you have to pay storage fees. Then, when you want to get a kit from "storage", pay for it on eBay from the savings account. Chances are, you will have a lot more money and less pressure on your family to rid a garage or storage room of all those models.
Plus, you can constantly post about all the kits you "have" "in storage".
Tamiya paints are very forgiving. I have found you can apply wets coats, so wet that they appear to obscure details, but not enough to run. After it dries, it's magically thinner and all the details are fine, along with a smooth paint job.
As for mist coats, I just move the can faster at about the same distance if doing a wet coat.
It's Climate change...
Come up to the pacific northwest. We have 0-40 percent of our usual snowpack. I work outside so see what's going on and this is the least snow I've ever experienced. Temps have been above normal for a month and we've set a few records. Will we regress to the mean in March? Maybe. We'll see.
In Spokane, we've had just the opposite. Record stretch for days over 50. Snow pack is abysmal. Hasn't been below freezing for a couple weeks. Very unusual for us this time of year. Not complaining one bit.
I think there was a mini dark age at the end of the 90s and through the early part of the century. AMT, after making nice models of just about everything (Pontiac Catalinas to Ford Explorers) crashed. Other makers had a few cool things, but lots of reissues.
I think, looking at what's coming, this year is a global push - and somewhat unbelievable at that. I know I won't have nearly the time to build all the cool models slated for 2015.
