The boat trailer guide base that I made today is made of mild steel that I painted with rustoleum (thanks to advice received here).

A concern expressed here was that when it contacts galvanized pipe or trailer frame, it may start to corrode quickly due to interaction of steel and zinc. To this, I want to say that if necessary, I could put some gaskets or other insulating material between steel and galvanized steel. I especially do not want to ruin the frame of the trailer as it cost me $2,800 and is in a beautiful shape 4 years after I bought it.
Any thoughts on protecting galvanized/steel contact areas will be appreciated.
