I use an Undercoating gun that I bought at a retail store that sells automotive supply stuff, and also recycle my used motor oil for this purpose.....
There are different schools of thought on this practice though. People will tell you that it's messy, (it is), others will tell you that the acidity level in the oil from being used, is not good for your truck....(I beg to differ!) I've done everyone of my vehicles since I first got each one, and the undercarriages and bodies look great on all of them. My 4Runner is 13 years old, and I see 99's or newer models for sale that are full of rust.....body panels and bumpers with holes rusted through, and undercarriages that are so orange....you'd think someone sprayed KD powder under the darn things!
Bottom line, in Northern Climates where Road Salt use is common practice in the winters, the only way to keep a vehicle from rotting is to spray it with a rust inhibitor.....motor oil done by you = CHEAP ALTERNATIVE!![]()
Thanks for the tips. I've never actually seen a 3rd gen with rust holes in the body ever haha, Canada must use some super crazy stuff on their roads. I can remember going crazing over 3rd gens when I was a kid, can't believe that they're 10+ years old now haha.
I checked out the undercoating gun online.. now I just need to get me an air compressor too. I'm really lacking in tools lol.
