So as you guys have probably noticed, I'm trying to get my console ducks in a row... fixing up issues, buying flash carts, ect. Next on the agenda is the snes. The top half of mine is from that dreaded bad batch of plastic that turns a gnarly yellow over time. Sally's #40 to the rescue!
I thought I would try it on something smaller first.... The gray plastic panel on the inside of my snes program pad had also turned a nasty yellow color. I forgot to take a pic, but imagine the ugliest snes you've ever seen.... it was one shade yellower than that.
So I brushed the stuff on with a paint brush and did a THIN layer. (That's where people with streaks screw up... more is NOT better.) Then I stuck it in a zip lock bag and left it outside in the (overcast) sunshine for about 6 hours. It isn't back to the stock color, but it's remarkably better. So much so that it registers as gray by the eye again and I've decided to stop here and put it back together. I'll upload some pics as soon as the parts dry and I put it back together.
The snes is next, but I probably need to wait until I have a sunny string of days as "close enough" won't work when only the top half of the case is yellow.
All in all the process was pretty painless and I wonder why gamestop and other video game stores don't re-label the stuff and start selling it in their shops along side the cleaning kits.
