Looking to clean up frame and undercoat 05 Silverado. Not going to remove bed or anything just going to work on this as time permits. What is the best way to go about this and what product do you recommend?

Clean underneath with power washer,buy a quart of Por 15,an assortment of foam brushes and wear protective clothing,and paint away. Por 15 is a great product.

You will get best results if you wire wheel. Easiest way is to pull off the bed, wash, wire wheel, and then paint. Pulling the bed makes access easier and the rear of the frame will likely need the most attention anyway.

 

POR15 is awesome stuff.

Go to town with a wire wheel on a grinder or die grinder, it's a good idea to take off any scale.

 

Then go over with a product like POR15 or similar.

Don't expect doing something like this to really help, unless you do a virtually perfect job.  Places where you don't get the por15 will rust, and it works under the por15 from those spots.

 

I would suggest regularly spraying the underside with something like Fluid Film, or even used motor oil.  Messy, but fairly effective at keeping rust at bay...

I'm a firm believer in Fluid Film.  My truck came from road salt heaven (Canada).  It was Fluid Filmed early in it's life.  9 years later and only have minor surface rust.  Heavier rust in the spots where the fluid film washed off.  I'm going to reapply before winter hits.

Goop enough crap on that..out of sight..out of mind..ha   Reminds me of my old XJ jeep.  It about broke in half when I took it wheeling.

If you want something that looks nice, you can get woolwax or nh oil undercoating with a black tint. Similar to fluid film but they dont wash off as easily

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
