I couldn't find a general frame building thread, so I thought I would try here as my query is about treatment, once a frame has been built. I just took delivery of one of the last new BOB Yak trailers, which are now sadly discontinued. The frame is made of welded 4130 chromoly steel tubing. At many of the joints there are holes by the welds which have been left unfilled, an example is shown in the photograph below.
I would like to prevent corrosion of the frame over time from the ingress of water. Should I fill the holes with black mastic; inject Waxoyl or Dinitrol before assembling the trailer; spray a teflon lubricant like GT85 or WD50 inside the holes from time to time, or something else?
