Cavity wax

Is there a brand or brands of cavity wax that are better than others?

I watch Vehcor on YouTube, and he mentioned that he uses two different brands. One that flows better for getting into seams and a thicker one for exposed areas. Only thing is that he never mentions the brands, though you do see him using a can of Transtar.

I bought three cans of KBS, but then I found some major complaints about some of their other products, and now I'm not sure if I want to trust them.

Anybody have one that they can recommend?

This stuff will work as well. Lanolin.

I'm a big fan of the Fluid film, and now they call it Woolwax, same shit buy no odor and slightly thicker. I've been using it for 10 years on all my vehicles, and for the fleet of electric utility trucks at work. We apply with the a specific air gun made to apply it, don't pressure wash the under chassis all winter, then in the spring give the underside a good powerwashing, then repeat the following late fall. subsequent applications are fast as it is usually just touch ups. I find it is great for areas that have surface corrosion already started, it seems to really slow down the progression. I use 3m cavity wax on new vehicles, or newly installed underside components, like brake line fittings, etc. Some will bitch about the mess if you need to do a major job on the underside of the vehicle, and they're right, but before i send a truck out to have major work done we use the heated pressure washer to clean the underside first, then after we get the truck back just reapply if it is still winter, and salty roads. The mechanics seem to appreciate the effort. I have a place an hour away that I order from called


free shipping on orders over $49.50. They have the guns too. We order it by the 5 gallon pail and have found the pro gun works best, I have the standard gun at home and it still works, just not as fast. We have found that some people have a sensitivity to the product, it just irritates inside their nose, but a N95-N100 particulate mask solves the problem. Unlike the old used motor oil treatment, it does not attack rubber or plastic.

There are a few around me that shoot it as a side gig. I find it best to use a lift, but lying on your back works too, just get the vehicle as high up on blocks as you can to cut down on fatigue.

I don't use my lift or garage to apply anymore since I started on my 68 firebird project, as I don't want to chance my project getting any of the over spray on it. I can imagine that corrosion proofing and autobody work should not be done in the same shop simultaneously.

Oh and I put sheeting or cardboard on the concrete under the lift to help with easy clean up.
 
fluid film fan for 20+ years. Only thing I found that holds up to the D.O.Ts salt / brine regime around here. Krown is rumored to be just as good (oil based)
 
Can anyone comment on how Fluid Film compares to CRC Heavy Duty Corrosion Inhibitor? Project Farm on YouTube seemed to prefer the CRC stuff over FF, but as well intentioned as he may be, his tests may not always be as accurate as real-life results.
 
I've used a lot of the Transtar in the past. Mainly cause that was what my Jobber had. They have a nice extended nozzle that they sell as well.
Would you have a number or more info on the transtar stuff? Needing to purchase some and not sure what to get. Thanks .

The extended nozzle kit is Transtar 4471


The rustproofing itself (aerosol can) is Transtar 4423


You can find it cheaper than in the links I provided. Those are just for reference. Autobody Toolmart is overpriced.

 
I've used fluid film (sheep dip) :D for over twenty five years, I like it. Liquifies with agitation so you can shake it and spray or brush it into place or you can brush it thick and as the vehicle is driven it will liquify and run down further into cracks and seams. I have a jag that I put some in the wheel arches from the inside, for years when I'd drive and park it there would be a spot of sheep dip on the floor under the front dogleg.
 
I've also used the KBS version with the long wand and liked it. Pick and choose products there, I use their tank sealer with good success. I no longer use their MCU paints since finding spi epoxy.
