Doing This With WD-40 Will Save You Thousands in Car Repairs

rev up your engines, now I've been using wd-40 for all kinds of things but it's come to my attention that there are some things you shouldn't use it for that I've seen people use it and cause problems so first I'm going to show you things you don't want to use wd-40 for now numero uno is don't spray it on squeaking fan belts or to be politically correct these days serpentine drive belts now if you got squeaky fan belts don't spray wd-40 on it I've seen people do it and yeah it'll stop the squeaking for a while but the belts are made to run dry this is a serpentine belt with all these grooves you do not want any kind of lubrication on them don't even spray any of that belt ease it says stop squeak and belt dressing these are made to run naked you don't want anything on them so if they're squeaking they're either worn out and they need replacing or if they're adjustable ones like my old Celica they need to be tightened up or if you got a modern car with an automatic tensioner you might need a new automatic tensioner but do not spray wd-40 on them now the next thing not to do is don't spray it on your tires to polish them if you want to make your tire shine use stuff like this blue shine that's made for shining rubber tires think about wd-40 a lot of it is a lubricant you don't want to lubricate your tires they need friction to drive down the road if you get it on the tread or it migrates till the tread you can lose grip if you're a hard driver especially motorcycle targeted treads that go way down the side you don't want to spray it on them years ago I had a friend do that on his motorcycle and he had a rocket 750 Suzuki and he was corning and he lost it slid on smash the whole side his bike scratched it all off custom of fortune and repairs and paint don't put wd-40 on your tires now another thing I don't advise people do with wd-40 is to spray it on your paint and then polish it off you can see it really makes it shine one over here shined up but this is something devious people do before they sell you were used-car it will make it shine like mad but it quickly fades off and then of course you got a faded car and if you do want to paint a car you have to have all that stuff stripped off it's not made for polishing cars only devious people do that and over the years I've had a few customers buy a car like that look real shiny and then a month or two later they brought it in said Oh Scotty my used car look the paint looks horrible and I look at himself she stick probably sprayed it with wd-40 and polished it all off so it looks shiny and the worst thing is I just shined this whole thing to show you it really shows up well in pictures so pictures of used cars look really good that way but hey you don't want to buy a car like that and you don't want to be sleazy and polished went up with it and then sell them to some poor person that finds out months later that the paint's all shot now there are some very good uses for wd-40 realize that it's got two main properties one is it's a water dispersant so let's say you go through flood water or you were dumb enough to hose off your engine bay with one of those big water sprayers that one of those do-it-yourself car washes and you got water and all the electronics you can spray this all over the electronics to disperse the water and the other property is that can loosen up rust particles so you got old rusty bolts nut you can't get off you can spray them all over let them soak overnight or a couple of days if you're in no hurry and they can do wonders on that and to prevent rust specially on bare metal or even painted metal that's old kind of crack they have these giant big blast ones I know guys up north they buy cases of this stuff and then they spray all around the bar and the truck and the wheel wells and the suspension arms and everything to keep all that salt water from corroding stuff in the winter and here in Texas I know guys that use in Galveston near the beach they'll spray their stuff to protect it to keep it from being corroded by the saltwater air that blows in from the Gulf and of course if you got squeaky parts or rusty parts under the car just jack it up here's why I like this cool wand this one came with so you can bend it and spray it wherever you want maybe your struts are getting a little squeaky the mounts may be ripped under there the rubber hey it's gonna help and you can go way up in the top spray that to not say I got squeaky bushings where rubber goes in you can lubricate them you can go up here spray anything that's starting to have a little rough so if you gotta take it apart later it'll be a lot easier and if you got an old-fashioned car like mine that still has a key you can stick the key in lubricate it all inside and quick wipe the excess off and of course you can do the same thing on your ignition key just spray the switch then no no we're gonna whine about that too sale style you shouldn't use it on locks well heck yeah there's a lot of other sprays you can use but I've been using this stuff for 50 years unlocks I never had a problem the wd-40 doesn't harm any electronics so you're doing on the ignition switch it's not gonna hurt any electronic parts if you have a system where the ignition switch is right on the bottom where the key is it doesn't hurt anything and yeah there's other stuff out there that people swear by but I've been using this stuff for 50 years I've never had to replace a lock switch on any of my toyotas and they do wear out eventually on Toyotas the reason I use it on locks is because decades ago a locksmith told me that's all he used he said I've seen you guys use graphite stuff and a graphite will build up and block the lock he said that's why he is wd-40 they don't block up anything and there's something you can partially use wd-40 for let's say your door hinges are getting rusty we're just opening it up and spray the rust hinges then you can't let it soak for a few days but then you should wipe any excess off and use this now this is wd-40 water resistant silicone spray it's not the wd-40 normal it's just the company makes the silicone spray too you can use any silicone lubricant you want but then you spray the hinges with the silicone lubricant because that's a pure lubricant and that will lubricate it over time the wd-40 isn't lubricant it can Lube a little bit but you'd want to do hinges any kind of thing that moves with an actual lubricant so it's lubricating while you use if you use a wd-40 you'd have to keep spraying it on because it's not gonna lubricate it over time and the noise had come back but with this the silicone stuff is pretty water impermeable oh you can only have to spray it two or three times here and the squeaks will probably go away, one thing I like about the regular wd-40 is they got these cool little tiny cans I leave them in a trunk of my cars so if there's ever any kind of an emergency I like so maybe you go through a big puddle and the car stops running cuz everything got wet you can get this out you can spray it all over the electronics so that it'll disperse the water and you'll be able to drive out a cute little handy things and on you get some crazy squeak that's driving your nuts while you're on vacation you can just get the little can out and spray it away so now you know things you shouldn't do with wd-40 and things that you should do with it, so if you never want to miss another one of my new car repair videos, remember to ring that Bell
