Beap52 1,330 #1 Posted June 10 my 1992 GMC K2500 elsewhere is my daily driver, however I don't drive a lot of miles about two thousand so far this year. One thing I have been doing on my vehicles the past fifteen years or so is using my pump up sprayer and coating the undersides and inside the fenders with Penetrol. Penetrol is used in oil based paint to help it flow smoother and I'm sure the main ingredient is linseed oil. It's been two or three years so today I crawled under and touched up a a few spots. 2 4 1 Share this post Link to post Share on other sites

ri702bill 9,187 #4 Posted June 10 I am a fan of using Fluid Film. It leaves a dry-sticky waxy residue once sprayed on. Messy to apply, but a good excuse to wear & toss the gaudy flannel shirt Aunt 'Tilda gave you last Christmas!!! 4 Share this post Link to post Share on other sites

squonk 43,323 #6 Posted June 10 In the mid 87 year GM switched to the new trucks with the boxed in frame as opposed to the C channel style. The main issue is the crap that gets inside the frame. I lost my 2013 GMC last Sept to a rotted frame. I saw a tool pop up on FB that looks to be a neat idea to wash the inside of the frames out. A magnetic swirly gig sprayer called the chassis grenade you pop on a frame hole and let it rip! https://www.saltycaptain.co/products/4wd-wash-chassis-flusher-kit I bought a clean Honda Ridgeline to replace my GMC and bought a Woolwax undercoat gun kit and used PB Blaster Surface Shield on it. I got back underneath it this spring and it held up well thru the winter. Also enrolled in a local car wash monthly unlimited wash club that will be worth the cost in the long run. https://www.woolwaxusa.com/Woolwax-Pro-Undercoating-Applicator_p_16.html https://blasterproducts.com/product/surface-shield/ 2 Share this post Link to post Share on other sites
nylyon-(Admin) 7,858 #7 Posted June 10 When my son bought his Rubicon, first thing he did was take it to get Fluid Filmed, great protection, but messy as hell. We added brighter backup lights to it and had to deal with the greasy mess of the fluid film, but way better than the crusty rust. 3 Share this post Link to post Share on other sites

peter lena 9,184 #9 Posted June 10 @Beap52, been rustproofing forever , like a 2 step process , a lighter chain and cable spray MACS / NAPA , as the initial tinniest , closed seaming , spray down , let sit a few days , note SPREADING LUBRICATION STAINING , then over spray with a heavier open gear spray , to same areas , the lighter oil will attract / cary the heavier tacky gear oil into related seam areas . that lubrication staining is your proof of internal rust protection , all of my stuff has oiled seams , and zero rust / rot . all my doors , have oiled seaming , fender edging etc . amazing to me to see , close to new anything with total rot thru , really ? also use oils to preserve paint , and regularly buff out , dull / chalky horse paint , like a penetrating oil first , let soak for days , then clean cloth rub in / finish with mineral oil , again let sit / days . like a 6" electric palm buffer , with a cleaner wax , go very easy on it , if it breaks the grunge phase . it usually comes back , very deep / solid clear red , have that on my 3 horses , paint is perfect period correct , no rust , pete 1 Share this post Link to post Share on other sites
MainelyWheelhorse 1,344 #10 Posted June 10 My mother has a 2013 Honda Pilot that she’s owned since new. For the majority of the time she’s owned it she took it to the automated car wash that cleans the top and the bottom. I think she also took it there in the winter to get the combination that they sand with here off. The car barely has rust if any and it’s nearing 200,000 miles. Her mechanic was extremely surprised how clean it was underneath especially for a rust belt car, she may have had it fluid filmed as well. 3 Share this post Link to post Share on other sites
