One thing I forgot to mention. Wear something over your face to protect your lungs. About halfway through this process I looked at the denatured alcohol can and on the front it clearly says "Fumes Harmful." Don't be foolish like I was. Better late than never I suppose. After my parts were cleaned I moved them into another room in my basement and covered them to keep the dust off of them while I work on the HS Skins to get them ready for the big prime day!
