I've been leaving my tackle bag in my truck a lot lately. Have any of y'all done that and the sun melted your soft plastics?

My bags with my plastics stay in the back of my truck most of the time, bed has a cover on it. A few from last year ate sticking together a little, they spent the winter in the garage. I did notice the sencos from last year are a little on the soft side & don't last long but still work.

I keep my plastics in their original bags stored in 6 pack coolers, but very seldom close the top.
