    Appreciate the tips. Hearing you much more efficient DIYers outsourcing this makes me think maybe I can't do it. Sad.

    If we’re talking about wool wax or fluid film, this stuff is just lanolin. Im pretty sure it doesnt have any solvents in it (other than the propellants in the spray can variety). The stuff in gallon cans I believe doesnt realy have anything other than lanolin in it. Basically, it’s like petting a sheep, but for a long time. :D

    It’s smells bad because wet sheep with greasy barnyard-hair smell bad lol. :D:puke:I think Woolwax smells less bad because it’s a bit more refined

    An N95 is just an ordinary covid mask nowadays. It’s a probably good to wear one if you dont want the inside of your lungs to have wool grease in them. Same for eye protection, although I will say I could blink faster and more smoothly after a bit got in my eyes haha. ;)

    I bought this stuff below from amsoil and tried it on my trailer first.

    I first used my wire brush and took off all the visible rust I could get to. Then I painted everything with a high rust protection paint and let it dry for almost 24 hrs. Then I hit it with the stuff below:

    Thanks. Been watching videos for general application that weren't 4Runner specific. Just wasn't sure about how to clean out frame and how to fully apply the new stuff.

    If it’s had miles on salted roads, it’s good to run a lot of water around as much of the underside as you can and shoot water into the frame rails and so it rinses out the inside of frame. It drains out fine.

    But woolwax isnt really picky. Just wash off solid clods of mud. The idea is to coat heavily. If the frame is a little dirty, just make sure to put enough on that it will saturate through down to the paint.

    Any surface with a nice grease layer cant rust, because oxygen cant get to it.

    It’s not hard, but it’s tedious if you want everything thickly coated. Dont wear clothes you like when doing spraying, it’s messy.

    Other products like cosmoline, the amsoil stuff, crc, etc may be toxic because it might be petroleum based. Wool wax just come from nasty stinky sheep that don’t shower.

    There’s a guy a few hundred miles from me that applied woolwax to cars…almost 500 bucks. He had videos showing his process, and he was thorough. I was willing to spend the money, but he wanted the car for two days (he did a desalting treatment he wanted to dry before starting work). In the end I did it myself. I don’t criticize anyone charging 400-500 bucks to do these kind of applications, if they do it thoroughly.

    Awesome! Thank you. I have been washing the under carriage often since getting the 4Runner but never did the whole removal of plugs in the rails and washing inside. I didn't even notice any plugs to be honest. I will start doing that, let it dry and then give this a go. I mean, if it feels like I am completely lost once I am under there I guess I can just tuck tail and ask a professional. Thanks for the info. I think I can give it a go.

    No need to remove plugs to rinse the inside of the frame. Tons of holes all over. Just use a nozzle on an ordinary garden hose, spray into an accessible hole (front wheel wells has a few) and watch the water start flowing. All the holes everywhere will let you be as thorough as you want lol. I usually hose my frame and crossmembers with lots of water after running through mud or after winter. Even though I woolwaxed the inside, I hose it out to make sure mud doesnt get packed in there and start plugging up the holes, which will then hold moisture (which quickly leads to rust).

    The car care nut has a good video on frame construction and rust. It’s required viewing! The only thing in the video that made me raise an eyebrow is when he briefly suggests plugging up some of the larger holes. I would not do that, because you would just trap moisture instead of allowing to dry out. Yes they rust from the inside out in those areas, but probably from a lack of attention. Dont plug these holes, just use them to rinse out the inside on a regular basis. These holes also give you good access to get a good woolwax coating inside them.

    One more thing…a thick woolwax will look like absolute crap after running it through mud. But it shouldnt matter as long as it’s coated well. I still rinse off the surface well, but the coating remains. If I feel like adding another layer, Ive done so right over the current coating.

    This is what mine looks like after I washed off the mud from an off-road trip:

    One more, one more thing :) These kind of coatings don’t really dry. If you use jackstands, make sure to wipe the the frame (to the paint) on the spot the jack makes contact so it doesnt slip. Recoat that spot after you are done.

    INCREDIBLE POST. THANK YOU x10. I appreciate the breakdown. I am definitely doing this from now on. Glad you wrote it out simple for a novice like me. I would have used a powerwasher in those holes lol. For some reason I almost felt like washing the insides would lead to rust. Zero rational for that. Once I wash the inside, how long to let it dry before I hit it with the woolwax?

    How do you know its time to recoat? Annual?

    And sounds like I should use woolwax instead of fluid film. Why? Cause you do lol

    Thanks again!!

    Edit: Watching video soon. Thank you for that link too!

    Haha. I would give it a day to dry…but it would probably go on just the same even if it’s a little wet.

    Woolwax is thicker and smells less than fluid film. Fluid film is nicer for areas that you might want it to creep a bit more.

    Recoating depends. I’ve only done spot touch up. If you get the inside of the frame real good, you might not need to recoat those areas for a long time. But the front of the a-arms, the front of the rear axle, all those areas will see some erosion of the coating , so those might need touchups as needed.

    I dont regret putting on a real thick coat on things. But some people spray on thinner coatings. In my mind, I want thick, seems to make more sense.

    I got a combo of spray cans for enclosed areas, and a gallon bucket for brushing or loading into a cheap paint sprayer I bought.

    keep it away from the cv boots, as it will pick up grit and grind at the rubber (I would guess)

    I think fluid film suggests at least annual (possible twice a year) and wool wax annually and surface blaster says ever 2 years. Me, I’d hit it twice a year for the first couple then before winter each year, but I’m in southern Maine and if seen some rusty Toyotas in these parts before.

    I truly think the best would be to use fluid film the first round, it creeps the best they say, then switch to one of the others after. I had my runner sprayed with surface shield in the spring right after I got it, and just ordered my gallon bucket for the fall spray. Once I see how well it held up over the summer and how well it looks after the winter, I’ll decide if it was worth it. When I had my Taco, fluid film worked awesome, frame looked great when I traded it in, but I didn’t help me in the trade value.

    Regarding the trade in value, I guess that’s not surprising considering the money people pay for these things with clapped out frames. Dealers are always gonna say trade ins are commodity vehicles, even if they turn around and sell it in the showroom as a cream puff for tons.

    Going through the trouble of coating is more for my own benefit. since Im planning to keep it for the duration.

    The only possible way to get any sort of return on a well preserved frame, is to sell with patience, waiting for the right kind of buyer who would be excited about a clean frame (they’re not all that common).

    Ya, I didn’t think I was getting rid of it. So hopefully the runner stays along time.
