Can you please post the link? Because I'm unable to find this reddit post no matter what different search terms I use. Without seeing the post it's all very well to have one person say that this caused their consoles to disintegrate within 3 years, but what about the many out there who have been retrobrighting since the early 2010's with the full sun plus chemicals? Shouldn't they have been kissing their plastics goodbye by now? At most what we've heard is stories of the yellowing coming back which means having the repeat the process again. This is one thing I'm not comfortable with as we still don't know what repeated retrobrighting will do to the plastic but considering what we already know about UV and it's long term effects on plastic I'm not keen to find out. Look I'm under no false impression that there aren't any risks associated with the sun and plastics. I think anyone with half a brain knows that if you leave any sort of plastic out in direct sun, especially in Australia, that over a period of time the plastic fades, degrades and becomes brittle. So I don't think anyone is completely unaware of the dangers. The thing is though the damage you do see from plastic out in the sun is from plastic which has received day after day, month after month of UV exposure. So in other words they have been copping a long term exposure to UV (and heat I might add) which is not good for the plastic. But at most these plastics are getting a couple of days of direct UV exposure and that's it. I'm not going to be silly enough to leave them sitting out there for weeks on end.
