Anyone here use Woolwax?

It's a metal seal rust preventative.  Since my Frontier got so rusty I'm going to try and head it off early in the life of anything else I own.

Comes in everything from rattle cans to jugs to spray on.  I wonder how it differs from any other product.

I used it on my Suburban. It's much thicker/gooier than most of the other cavity waxes I've tried, which makes it my favorite. Makes wrenching on stuff a bit of a mess, but it doesn't seem to wash off and so far seems to be doing its job well on my truck.

(Somewhat) relevant Project Farm video. He doesn't test Woolwax, but he comes to the conclusion that the CRC stuff is the best of what he did test. I've used both that and Fluid Film. The CRC stuff tends to flash-dry more quickly, and I think it stays on surfaces longer, but Fluid Film is thinner and will a do a better job of seeping into cracks and crevices, IMO. I use both.

B'laster Surface Shield is supposed to be the hot ticket for longevity (2 years supposedly) because of its wash-off resistance and how it creeps. It used to be twice the price, so it wasn't really worth it IMO as you touch up the coating every year. It looks like it's reached price parity these days so maybe it's worth a look.

Fluid Film smells awful, but its what the Coast Guard and Navy use on their aircraft as part of their corrosion prevention programs. It self heals pretty well and does work being the OG of the lanolin coatings.

Woolwax works well, and doesn't reek like Fluid Film, but be aware that it is thick so it doesn't creep as well. There's a LV (low viscosity) version for places where you want it to creep into seams. Eg: bottom of doors.

Like a helmet, the best one is going to be the one you use and keep using.

I've looked at tests recently as I've always used Krown but it is washed off the underside pretty quickly.

 With the intent to keep the new Ridgeline a long time making sure crossmembers and attachment points remain solid is a concern.

 Couple comparison tests I watched had Waxoyl well above the others in durability/protection.

 More research needed before I commit since the closest Waxoyl to me involves crossing the border and going for a 6hr round trip.

I used Woolwax on my Frontier, I like that it never dries or seals, but it is fairly thick stuff so I still pumped motor oil into my frame since the Woolwax won't creep much. I got a paint can of the stuff, and they also sell a spray gun you hook to your air compressor, it works pretty well. I did my truck fall of 2022 and you can still see the Woolwax on various seams and surfaces, it will wash off with any sort of high pressure water though.
