Just started using HD Metal Protector & it’s hands down better than what I’ve been using, can see the coating still on bare metal & no rust!

You name it I've tried it when it comes to products that claim they prevent rust or stop rust and some are good don't get me wrong I'm talking major brand names to Independent chemical companies and I figured I'd give Amsoil a try and I literally put it on existing rust and it stopped the rust not for like a week or a month but permanently and I did the underneath of my Toyota 4Runner from front to back and is anybody knows in the Rust Belt most products don't hold up this not only holds up but I'm just sorry I didn't find it years ago Amsoil really is the best I admit this is the first product I've ever used from them but now that I've seen what this can do I'm going to try the other products too.
It soaks into the metal fast and takes the rusty look away..
Bottom Line
Yes, I would recommend this to a friend.

Top Notch Metal Protection

Having been using the entire range of Amsoil products for my vehicles and motors for a very long time. Purchased a new 23 Toyota Tundra recently and wanted to help protect the frame/components from the Northeast winter salt. Applied MPHD to the entire underside of the vehicle, simple process overall and when dried it created a nice barrier from all contaminants. Truck has been driven in snow/salted roads and after being washed all exposed metal still looks brand new, highly recommend this product.
Bottom Line
Yes, I would recommend this to a friend.

I would recommend to anyone who wants to DIY rustproof their car, truck or anything else that will rust. Plus it goes a long way. I did my Yukon XL with less than 2 cans.

MP-HD PROTECTOR

Great product it works great for keeping rust off of my tools in my garage .also use it under my lawn mower decking to stop rust and to keep the grass from sticking I highly recommend this product
After debating whether to undercoat or use this product to protect frame rails and undercarriage, I am very happy that I listened to others reviews on this product. Turned out amazing, was easy to apply, and seems to be very long lasting after cured. Ordering more to have when needed.
HDMP has been a necessity in my shop for decades. It gets used as chain lube, protection from the elements on my little sawmill, hinge lube on every vehicle, on and on. Just a super useful product!
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.

Keeps your under carriage looking new.

Great product, keeps your under carriage looking new. Note; make sure you follow the directions.
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.
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.
