PETG is definitely stronger and is reported to be easier to work with (bends easier) than acrylic. It not being UV resistant like acrylic is though could be an issue I would imagine. Will it yellow or possibly become more brittle over time or who knows what else if exposed to sun or UV lights? Also the fact it is hydroscopic (absorbs water) similar to flexible tubing I suspect could mean it might be more susceptible to staining by dyes/coolants. I don't know the answers to any of those things though as I won't be getting any PETG myself at least not for a while until some of those suggested possibilities of drawbacks from ways it differs from acrylic are confirmed or ruled out.

Is PETG being offered anywhere in any colors like acrylic or just clear?
