First posting. Good Day all. Thought for sure this one would have filled up quick.  A tip I use quite often, is to use a silver "Sharpie" to outline both sides of a parting line or spot super glue, I am sanding, to see how much work will be involved with it. It is faster than opening and closing paint bottles and you don't have to clean the brush out. Downside with this technique is that the ink in Sharpies is thicker than most brush paint and needs complete removal before any other color coats go on. Use regular old "dry gas" to remove this. This stuff is very bad for you, in more ways than one. Use with extreme caution.
