    Default Aluminum filling

    I have a couple of small holes in side walls of a caravan and some small dents.

    What is the best way to fill and what is the best product to do this with.


    Thanks

    We would do it in the same way we do a hole in steel. Plus, if possible, put some sealer on the opposite side.


    After cutting the rust out back to new metal grind the surrounding metal clean then countersink the edge of the hole and apply a "good" aluminum tape then cut the tape so that it lies within the sunken area. Using a rounded tool (like the end of a screwdriver handle) press the tape edge so that it gains maximum adhesion to the metal then lightly scuff the aluminum tape with 80 grit being careful not to tear the tape. Apply the fiberglass filler making sure to press it into the surface so that it will adhere properly then sand and apply body filler to fill the indentation.
