Just trying to figure out which way to go here. Im 24 and recently picked up an abandoned tail kit. I was thinking about etching/alodining everything. The alodine is supposed to protect from corrsion so is there any real point to priming anything that wont be out in the weather? Would like to keep it as light as possible so thought the lack of primer may save a pound or two plus some time and money. If I were to lose my medical around 70 and die flying around 90, thats 66 years Id like to see the thing last (OK maybe I'm a little optimistic), do you think the alodine alone would be enough? Going to try and get my hands on some powder so it will be affordable. Looking at the Iridite 14-2, does it matter what I use to etch with, I thought most alodines were an etch/alodine system but I havnt seen what is recommended with the Iridite. Thanks for your advise.
