I read in a KO review thread that somebody was going to boil their toy in water to remove the stress marks. Sounds like a neat idea right? I tried it last night to see what would happen. I took a brown piece of plastic (not transformer) and using a few wrenches bent it and created a white stress mark down the middle. Mission accomplished. I was boiling water for some pasta at the time so I thought "well I'll just dump the used water into a container and put the plastic in there." I left the plastic piece to sit in the used pasta water for about 20 minutes while I ate and checked on it. It didn't work Oh well I thought - let's try it with real boiling water in a pan. Put a little water in a pan, boiled it up and dropped the plastic in. I checked back a few minutes later and I didn't notice the stress marks. So I took it out with thongs and it seemed to work! The white was gone and the brown had been restored. Now to test on a real transformer, but I imagine it will work there as well. The only thing I'm concerned about are the stickers. If I dunk a stickered toy in there I imagine the stickers will be destroyed. I guess I'll find out in my next test. Reprolabels to the rescue if the stickers fail.
