Ok car is rusting away need ideas cheap ones

[BigRich954]

I have a 2000 car the paint looks great but the whole underside and engine bay is rusting away. starting to flake out so the steel is weaking alot.

I was hoping to keep this car for 2 more years but worried it wont make it.

I now live in SO CAL ow so it should slow the rusting down. but i plan to drive north and do camping trips (snow)

Whats the cheapest and easiest way to slow the rusting down ?

Or just drive it till some things falls off ?

paint and prep from home depot, apply it with a spray bottle or brush , it turns red oxide (active rust) to black oxide (inactive) . Its $15.XX a gallon, wear gloves if you brush it on or a mask if you spray it , it also will kill your grass so be careful where you apply it. You can find it in the isle with the turpentine , solvents etc.

is the name "paint & prep"? What is the active chemical? See also the thread I started on Krud Kutter.

Yes its called paint and prep , it`s phosphoric acid , also called Ospho , it works great. take a look on the Home depot website to see what the container looks like.you can paint over it after you let it dry for more protection.

paint and prep from home depot is it more like a water thickness ?

cause i think spraying is my only way to go i want it to get in all the cracks and holes

Is there anything i cant get it on? tires/wires ?

iirc the frame rusting out was one of the reasons that sciphi traded in his early 00s buick for the cruze.

Yes its like water and is very good at getting in behind and under things , I spray it on too , I use an old windex bottle or what ever empty spray bottle I have around , just rinse it well before using it.I wouldn`t spray it on tires or wires if I could avoid it , that said I have not seen it attack plastic or rubber.You can always try it on some test items to see what it does.

Wow your on point thank you

does it have to get painted or will this be good enough to slow it down or after i treat it maybe spray it over with wd40 and call it a day

 

[05GMC]

No , you don`t have to paint it , just keep an eye on the area and if rust pops back up give it another squirt , please , wear a mask if you intend on spraying it , its acid and that can`t be good for your lungs , if you get it on any small cuts on your hands you`ll see what I mean.

Buy a respirator since you're working with that stuff. Your lungs will thank you! Also, be sure to wear a long-sleeve shirt and double-layered nitrile gloves. Can't be too safe working with a potent chemical like that.

And yes, I traded in my 1999 Buick LeSabre on the Cruze in my signature since it was shot underneath. It ran like a million bucks, but the subframe mounts were rotting away, a massive piece of rear unibody reinforcement was about to let go, and the rear wheel wells were disintegrating. There were spots I could have punched through with my finger.

For protection on the Cruze, I sprayed 6 cans or 96 fluid ounces of Fluid Film into every nook and cranny I could access on the underside. Wheel well liners and sound deadening panels were removed to gain access to all the little nooks salt will build up this winter. There's another can going into the doors and down into the rocker panels soon. Hopefully that will slow the rust down a little bit.

What parts are you talking about? Rocker panels? Floor boards? I assume you're keeping an eye on your brake and fuel lines.

Post some pictures?

Often when you see rust on rocker panels, it's started from the inside out, and the paint is just holding things together when you see it. If that's the case, chip away the rust. Get a $12 angle grinder from harbor freight with a cut off wheel and trim back to good metal. Then treat the insides and shiny surfaces with rust treatment of your choice. Then get "tin" or a thin metal of your choice, make a metal brake with some 2x4s and C-clamps, and rivet or screw them in place. Seal with bondo, seam sealer, silicone caulk, etc.
