    Amsoil HD metal protector works great,( aka. cavity wax) I intentionally had to remove it because It does not wear off and this was my test, I put this on my lawn tractor appox. 10 yrs. ago. the part never rusted and did not come off. This product can be used inside car doors,quarter panels, trunk lids cab corners and so on. But the area should pretty clean first, I think so anyway. pretty tough stuff!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product

    My main use for this product is vehicle undercoating. It works great at protecting everything on the chassis, including subframes, suspension components, hardware, brake calipers & shields. I also use it to protect vulnerable body panels - especially inside the quarter panels and lower sections of the doors. I reapply every year or two, more often to high exposure areas. It's helped my 12 year old car hold up well against harsh winter salt. Amsoil HDMP is a good value compared to similar products and the extension straw is nice for tight spaces.
    Bottom Line
    Yes, I would recommend this to a friend.

    Impressive !

    I decided to try this in a marine and off road applications and it has only been in use for about a month now. So far the results are looking good. Time will tell. I like the ability of 1 stop shopping with AMSOIL, so most likely this will be a standard shelf item... Looking forward to try more products from AMSIOL.
    Bottom Line
    Yes, I would recommend this to a friend.

    sprayed the underside and rocker panels of my new F150 in 2011 with a few cans of Heavy duty metal protector. 10 Minnesota winters later no rust anywhere, that includes axles, suspension and shields. Dries to smooth finish that does not attract dirt or water
