I would like to build a LEGO model which is unbreakable.
What is the best approach?
I am not looking for just glue here.
I don't just want to strengthen the bond between the bricks, but the model as a whole. The level of force to withstand is in the area where it would actually break a single brick.
Has anyone tried the kind of spray on film you can use to protect your car from bumps? How does these kind of product react with LEGO plastic?
Also important is that whatever I would use should not add a thick layer on top of the LEGO, it needs to retain it's original size to some extent. A millimeter or maybe two in some places could be ok.
