    Bonnet: how to clean it

    The bonnets are usually very grungy and dirty underneath.. they were not painted apparently . Has anyone got a suggestion as to how to effectively clean them...and achieve that bare aluminium look. The problem is: the many rivets and associated ribs make it hard to clean . Maybe glass bead blasting .

    I am wary of blasting large wide panels with beads, because of the risk of localised heating; however; a good degrease followed by soda-blasting appears to be the answer.

    Check out the website of Western Soda Blasters. I plan to have all of the body soda-blasted on my car; apparently it will remove paint but not damage glass

    Bonnet rebirthing

    Hi All
    this what I did
    knock all the rivets out
    using paint striper and a steel scarer and rub the underside
    when clean rub the whole bonnet front to back with the steel pad to have the rub marks running the same way
    clean the galv. with the same steel pad and Black and Gold vinegar
    then put it back together.
    only takes time the results are very good
    cheers

    I used a steam cleaner on a gearbox. It stripped off 30 odd years of gunk without much effort.

    I would not grit blast with glass beads - they are too hard.

    But there are a wide variety of materials that can be used for grit blasting - and there will be something available (such as crushed walnut shells) suitable for cleaning aluminium. Have a talk to a sandblaster, or even an equipment hire place that hires out sandblasters.
