Bondo vs formula 27 vs epoxy fairing

If the salt water can get through the outer coating to the talc body filler and the metal under it you will sooner or later have a mess. My truck and trailer need to be redone and they both had been down to bare metal with an epoxy primer on everything.

If a person can do it the method you described....



...is by far the best solution,

Yes, and that's just a one-time immersion. Constant immersion creates condensation on the inner skin, hence the common practice of insulating the interior to try to minimize this. Marine products often cost more for good reason...

The worst part is: I won't know which way was best/cheapest/easiest for like fifteen years lol

Remember if you use 407 you shouldn't apply a poly product over it. You can apply epoxy over poly but not poly over epoxy. Just one of the reasons it's best to stick to one product. I think Rage Gold comes in four gallon cases, I bet my cost is about $100. Probably enough to do your whole boat if you are just spot repairing...

Unfortunately about a weeks worth that year and other years water is there, but not as deep .

Sounds like you can help him out ,

Thanks one and all for the help on this thread. I thought I'd share some pictures, I think it turned out pretty damned good. Hopefully it'll last a couple years

Nice!! Congrats on a good job.

Just be careful epoxy resin is flexible and reactivates with heat not good to paint over in dark colors and shows small stress cracks around tension areas. In Australia we use epoxy resin mixed with micro balloons or spheres or Epoxy resin mixed with Q-cell all light weight compounds for faring easy to sand, you will need a sense of humor and a good torture board to get your boat straight but possible and worth the work.
