Okay, so my new to me boat needs a bellows job due to a leak I posted about in another thread. Since I'll have the boat out of the water, I figured I would go ahead and repair some drive corrosion. I've searched a lot of threads and I'm not sure what the best steps are, but this is what I've found. Keep in mind my boat is in freshwater.
1. Sandblast the drive with walnut media
2. I'm not sure what to fill the corrosion pitting with yet.
3. Etch/prep bare drive with Alumnaprep 33
4. Alodine the drive until it has a golden tint
5. Polyurethane epoxy primer
6. Polyurethane black
What do you guys think? Is the walnut a good media to use? I'm not sure what to use to fill the corrosion pitting. I've heard not to use jb weld because it has steel in it that will react with aluminum. I've also read that people have successfully used jb weld for yeas.
What do you guys think about the poly paint process? Is it needed or overkill. I'll be spraying with an hvlp gun. Let me know what I've missed.
Here is a picture of the drive. Should I get the Skeg repaired? It's another $200 added to my already growing bill. I've read some say it's not needed and some otherwise.
