    Have to butcher the outside of our MH and cut a few holes so want advice on the best way to treat the bare areas to prevent corrosion.
    First up is 2 dead locks getting fitted to the front metal doors , so whats the best way to treat the bare exposed metal.
    Second up is the Gas it re filler which is getting a hole drilled in the Aluminium skirt. now i know that aluminium does not rust but it does corrode which causes the paint to come off and the corrosion spreads, so again whats the best way to treat this bare area.

    Thanks

    A coat of primer then paint.
    It won't be seen.

    Use a good quality hole saw in the first place, then invest in a can of U-Pol acid etch primer to treat the edges after to have cleaned the burrs up with some wet and dry. The acid etch works on aluminium and steel.

    I give it two coats of primer then top coat as needed.
