    Default Drilling holes in trailer

    Hi

    I've recently bought a Wilderness 310 and had to install a new fridge slide as the slide that came with the trailer was too small. I had to drill new holes for the bigger slide. Do i need to apply something to the newly drilled holes to prevent rust or can i leave it as is?

    What can i use to cover the old holes?

    I've aslo realised after my first trip that the ammo boxes rubbed the sides inside the trailer and removed a bit of paint. Will this rust if left untreated?

    Use silicon with washers to seal new drilled holes.
    Previous holes can be sealed with flat galvanized gutter screws and galvanized or stainless nuts underneath with washers and silicon sealant .

    Be aware that many silicon sealants contain acetic acid which may accelerate corrosion.
    Rather get the appropriate Sika product.

    Thanks Sam you are correct, even the black car silicon may cause corrosion on mild steel.

    I would apply an anti rust primer eg red oxide to new and old holes, allow to dry then paint over with a suitable paint. Once dry, then do as advised ie sikaflex silicon, washers and nuts etc.

    100% agree.
    If it smells like vinegar, DON'T USE IT on anything that isn't ceramic or glass.

    Sika, Reinzosil, Loctite, any "mechanics" sealer, NOT Bath, Car, Shower, etc silicons.

    When using small bolts and lock nuts for the new rails, remember to use locktight as well, believe me those lock nuts do come loose on bad gravel roads.
