Hey Guys, I've been reading the Board for months, thanks much for the education! I've just bought a Eagle 10 conversion. It suffers from some electrolysis on the aluminum skin, causing blistering along the beltline. I'd like to stop this before it gets worse. I'm sure it has to do with dissimiliar metals contacting one another. Any suggestions short of stripping the siding off? |

Randy, that seems pretty normal. I'm just going to sand mine out and either use bondo or fiberglass, most likely bondo. I have cut rectangular patches and rivited over bad spots in the past. Once its painted it looks like it belongs. |

Randy, I've been in the aircraft bussiness for over 28 years, remove old paintninto good metal, brush out surface corrosion with a STAINLESS STEEL brush. Purchase a gallon of ALUMIPREP 33 and a quart of ALODINE 1201 from: Aircraft Spruce and specielties, 877-477-7823. Use per the bottles and paint, will last forever.>>>Dan |

Thanks a lot guys, I'm going to take your advise Dan. I actually have the Aircraft Spruce catalog. I suppose to do it right, all the siding should be done. I am curious as to maybe also running the old style ground straps that drag on the ground. I also would be interested in the possibility of ingots attached to the monocogue, much like boats have, I think they're a zinc alloy, these are sacrificial and attract the electrolysis. Once again thanks for paying attention. |

Are you sure that isn't from salt corrosion? If it is, I don't think those choices are going to take care of it. It'll keep coming back, as the salt is wicked between the overlap of the panels over the years. I think that someone mentioned something from the boating industry that is supposed to neutralize the salt. |

John, Thanks for the response. Salt is not the problem, I just mentioned the use of zinc alloy ingots that salt water boats use to attract electrolysis. I thought that perhaps some electro-chemical engineer out there might have a thought on a prescribed alloy that might do the same for us. Thanks again. |
