I acquired a junker Masterpiece Shockwave. He is the...logical choice for this experiment. No matter how many times I look at this figure, I can't get over the terrible colours. I have a custom painted Shockwave but he is too fragile to transform, thus my desire for a dyed Shockwave. I used 1x bottle of RIT dyemore in royal purple 1x 100% acetone Big ass stockpot to cook everything in I added the dye and acetone bit by bit. I had the hob on low and boiled for about an hour, more or less. Sadly, after an hour of boiling and an entire bottle of acetone and dye, the result is poor. No warping or damage, but it looks as though the plastic wouldn't accept the dye. Back to the drawing board I guess. Maybe the professional dye is worth a try?
