I live in Australia where temps can easily hit the high 40's in summer, and have had no problems with sagging yet. Granted I keep all my models in cases in a cupboard, so they don't get any direct sunlight, but still it's not something I've run in to personally. It's certainly not something I would tolerate though if I ever did. As I understand it susceptibility to sagging comes from the resin not being mixed correctly, so it is entirely their fault and for the prices we are paying I should be expecting it to be done correctly or get my money back.Finecast is awful and that's only noting short term issues like poor casting, have you started to see warping and sagging pics yet? My metal minis (which were in the main part were cheaper than their finecrap replacements) haven't sagged over the years I've owned them but a empire witch hunter in finecrap turned all most like chewing gum on my window ledge in 24 degrees, next GW will be saying I need a gw branded display fridge for my minis!! I can't wait to see how this ***** holds up in the lighted cabinets at games day, although in a truth most competition painters won't touch finecrap because of all the bubbles, soft/wavy edges and missing details.
