Practice
It takes practice. I bought fiberglass cloth and epoxy to fix my sailfish. Put the materials in the paper bag in the tool shed. When I finally got to the job, I immediately put my hands on the materrials knowing they were in the original bag. The receipt was there too...10 years old. You can't learn this stuff all at once. Practice, practice, practice. (Originally bought the sailfish (used) from your neighbor on Mark Is. in the late 70's. Also bought a 26' Lyman and a 30' CC through him.)
