How this library is organised
Four of these guides are about money, two are about the law, three are about materials, two are about style and construction, and one is about time. Six of the twelve are San Clemente-specific and say so in the title; the rest are general because the standards and the physics underneath them are.
If you are at the very start, read refacing versus refinishing versus replacing first. It contains a five-minute physical test that decides between a job costing a few thousand dollars and one costing many times that, and everything else follows from the answer.
