Many of you have probably used this stuff, but in case there are those who haven't, it's worth considering. My airbrush skills are honestly pretty poor. My masking skills are even worse. I hate masking. Cutting pieces of tape or whatever else that is adhesive doesn't work well for me.It sticks to me instead of the item to be masked. Decades ago someone told me about a product called Parafilm. It is the easiest way to mask off parts I have ever found. It's basically a thin wax sheet that comes in a roll. The roll I have (pictured) is about 30 years old and still works perfectly. All you have to do is cut a piece off, warm it a little with your fingertips, spread and shape it, and press it onto and around whatever you need to protect from paint. You can use the tip of an Xacto blade to move it around in really tight places. When you are done, just peel it off. There's no adhesive residue to remove. You may already know about this product, but I thought it was worth mentioning. It is so easy to use. I have no idea what it costs now because the roll I have will last me several more years.
