Hey geezer. I'm going to give this a try. I'm not at all familiar with lapping films and I don't want to order more then I need. The vendor I'm looking to purchase from carries 0.3 and 1 micron film(they don't have .5). In your opinion would this work or do I need .5 film? I assume 1 micron wouldn't really leave a scratch pattern, just a slightly duller shine.
