I think this will be a simple one that I should already know but I don't. Most of the time we work with aluminum (2024, 6061, 7075...) and for nicks, gouges, scrapes...the disposition is to smooth and blend unless the discrepancy is greater than 10% of the thickness of the material then it is scrapped if a doulber is not an option. What I'm hoping to find out are there similar rules of thumb for steel and composites? Thanks.
