This product is exceptional. Has performed great in Michigan’s harsh salty winters on my vehicles. I highly recommend it for metal protection in such harsh environments.

I use this suff all underneath my car 99 z28. I put it on engine exhaust and everything it really acts as a barrier to the hard environments.

This stuff is cosmoline and it’s the best price for quantity that you can find. Works amazing as an undercoat for your car or truck, has held up strong through one New England winter so far.

This is a GREAT product. Only thing i dont care for is the color. Its a brown color and once it dries, good luck getting it off. Probably not possible but if it was clear, it would be 100%

Excellent product. I live in the northeast and this product has saved my vehicles. Without it they would have been eaten away due to salt and rust corrosion. This is a go to product for my workshop.

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

I'm using thus product and highly recommend it to others

This product leaves a heavy film on and surface I spray it on. This is very long lasting

Will never use anything but HD MP for all under coating needs. This stuff is very resistant once applied and the best part is that after it cures it’s dry to the touch so it’s getting all over you and everything else it touches after application.

Lubricates better than other products because it lasts longer and stays on the parts. Have used it for years on all types of metal to metal contact products.

Holds up very good New Hampshire winters are brutel on your undercarriage up here.

Amsoil MP is a great metal protector. I use it on my door hinges and on some electrical connections for my GMC power running boards. It keeps moisture out and stops rust from starting. Thanks Amsoil.
