I am thinking of using LEGO to make some outside yard art, (large minifig scale castle) and wondered what I should do to prepare them for being outside in variable weather conditions (in the Seattle area).
I am aware that Legoland glues their displays, but have not found any other details on their technique.
Discoloring in the sun is not a big concern of mine, other than I will probably avoid too many white elements which tend to discolor more noticeably.
As it's ABS plastic I imagine water wouldn't be a problem, and I should just be able to wash them down if they get dirty. What about snow/ice freezing temperatures?
Does anyone have any experience with outdoor displays?
