Like i mentioned before in other threads.
I use 210 on a regular basis. Signs have lasted 6 to 8 years and apart from about 1/8" shrinkage along the edges, The prints still looked good.
Either the south has received bad batches of the material or the sun is really beating down hard compared to the north.
The UV index is typically 3 times higher or more in the Deep South compared to the Upper Midwest/Canada.

Maybe hand painted signs need to make a comeback in the southern states.

I use 210 lam regularly. My signs aren't browning and I'm in the south, but I do see that same shrinkage.
I can tell the customer they need something more long-term (translate more expensive) that is better suited to the job. But the reality is most don't seem to care - price, price, price is all they seem to care about nine out of ten times. So they get what they pay for. However, like Baz, I have signs that have been out there in the hot Florida sun for 7-8 years and they still look pretty darn good.
why anyone would consider using calendared products for long term is beyond my comprehension. Even if it does last a few years..
