Re: Bottom paint on prop
For a bronze prop, use Petit Zinc Barrier spray. It's not expensive. Just prep the prop properly (nice alliteration) bringing it down to bare clean metal and then wiping it down with MEK or acetone. Spray only two or three thin coats 20 minutes apart. It has worked well for me with very light growth over the course of a season.
I've also had good results from the Petit zinc spray. Before that I tried several types of propeller antifouling treatments, everything except Prop-Speed, that was next. Last year I ran across the zinc spray and tried it and it worked really well. I had maybe three or four small barnacles attached to the prop, where before (with and without other treatments) it was fairly well caked with them. If this didn't work I was going to go to Prop-Speed. I still might try it some day but for now, the Zinc spray seems to work pretty well for my area.
