I gave a kit to a friend of mine recently. It was a 1/72 Hasegawa Tornado kit. I had the kit for about 15 years in my closet. For a few years it was stored with the rest of my " stuff " in a storage locker that was not " air conditioned ". The decal sheet looked fine however. No yellowing or fading as far as I could tell. Even though my kits were in storage, I kept them in covered plastic tubs. However my friend said that the decals ... when he applied them ... " crystallized " . I haven't had a chance to look at the model or the decals. But it got me to wondering how long decals last and maybe they just go ' bad ' after a while. I'm wondering if while they were in my storage unit if the heat/cold and humidity may have ruined them ?
