Rust proofing with cosmoline (1 Viewer)

[cruiserpilot]

Thanks very much! Your experience with the stuff really helps understand what's in each can. I saw that corrosive inhibitor on Amazon as well,
never heard of it before. I've sprayed the deck of my riding lawnmower with the Rust Check 3000, but I really don't think it would stand up to
real winter abuse so I opted to not even try it. I've researched for a long time, got a Tundra for winter work but the Cruiser misses the winter
road trips. I will make an order after the christmas rush and spray away.

Did you use the stutzh gun for the industrial stuff to spray it? Did you have to thin it? If so, how much and with what

Just to add one more data point; for inside body cavities (doors, fenders, quarter panels, tailgate, rear hatch, rocker panels) I've been using 3M CAVITY WAX.

3M also makes a kit to be used with the aerosol cans with three different length application tubes/nozzles, ~8", 24", and 36" long which allows you to spray deep into body cavities, often just by removing a screw or bolt.

It may be similar to some of the others, but no odor once the solvent flashes off, just leaves behind a slightly tacky wax.

IMHO a Key point is to not block any drip/weep/drain holes/slits whichever
product someone uses.

For example, the quarter panels on an 80 series, IME, have three extremely small weep holes where the different panel sections come together and which were left open, apparently on purpose.

On very close inspection (and from taking photos) looking up from underneath the quarter panel you can see where an assembly line worker stuffed body/seam sealer in some areas (by hand) and left other areas unsealed; those unsealed areas are (IMO) meant to drain water from the bottom of the quarter panels. I demonstrated that by pouring rubbing alcohol into the quarter panel cavity and watched as it dribbled out the very small weep holes, two of which were partially blocked. I used rubbing alcohol figuring it would evaporate quicker if it got trapped inside somewhere, but it all came out.

After cleaning out the quarter panel cavities by hand I followed that with the 3M Cavity Wax and watched it drip out of the (3) weep holes, again making sure the very small holes weren't blocked.

Ditto for the drain slits on the bottom of the rocker panels. To spray cavity wax inside those you can pull off one or more of the rubber plugs which face inward on the backside of the rocker panels.


FWIW.

Maybe you missed this question. Did the industrial stuff ( you said went on like 20W50 ) need thinning for a spray gun or did you brush it?

Cosmoline direct suggests thinning it, but I sprayed it on at full strength and am happy I did as the film is much thicker. I shot it out of an air-fed undercoating gun, 80psi seemed to give the best application without a ton of overspray.
