UPDATE: trailer paint prep
I've just been working way with the wire wheel, started with a brass wheel so as to work the rust off preserving the current paint. Plan on then hitting it with some good rust primer. In some areas I used a steel wire brush and got down to shiny metal wiping out paint and all. Not sure I have the time to commit to wheeling the whole thing down to shiny metal. The rust is really not that bad at all, but my perfectionist side is iching to pull every bolt and remove all the old paint... OVERKILL I am sure of it.
