I know - sure they will last but they won't work..... This is VERY selective painting. The Maxprop anode is a truly dreadful design. Anodes corrode from the outside so let's put the mounting holes as near the side as possible and sell more anodes..... We were losing them within a month so I decided to try painting the area round the mounting holes with liquid electrical tape. It worked perfectly. The anodes stayed on much longer and were more effectively consumed. The liquid tape seemed to hold fine given the somewhat hostile environment (painted onto a chemically reactive substrate being rotated rapidly in salt water was probably not on the list of applications tested). This would appear to be a Maxprop only tip but it may have other applications.
