So far I have always lucked out with new and used boards, for example this square logo which is year 88 only had 2 broken rivets, and as for the rest new and used ones either 1 or none, hopefully I will luck out. Anywas bolt mod is something I want to learn, but dont want my first board to be by any of the used ones cause they are all like new condition. I need to find localy some beat up, keycaps missing but functional without any spillage damage for $5 and this type of a board I would like to practice my first bolt mod. Once when I have done it, then the rest of the used boards I will bolt mod them, would not bolt mod the new boards though.
Exactly what I thought about removing the sticker and the residue, so far hot water + Dawn has done all the cleaning my Model M's needed, has removed also some stubborn glue reside, just needs lil soaking and leaving it to soften up a bit.
