2000 Silverado undercarriage had a fair amount of rust that needed attention and I just did not have the time.
Finally broke down and had it professionally done. All the rust was wire wheeled and cleaned up. Then a mixture of Raptorliner and flex agent was applied.
In October or so they’ll check over it again and any places that may have been missed or seem to need another application will be done.
They found a soft spot in the frame that would really have been just fine cleaned up and coated but it was right near the front jacking point on the frame so I had them repair that portion of the frame properly before coating. That way if I were to get a flat on the side of the road and have to jack that area up there would be no issues.



Very happy with the work. They took the time to remove the spare tire and drive shaft so they could spray everything evenly.







Had to have the rockers redone a number of years ago. Yeah time for new shocks I know. They’ll be replaced in the Spring.

That looks great!

That does look great, wish there was some place around me that did work like that, took my 2006 SUV to the body shop and they didn't seem interested in doing it. Vehicles rust bad in KS and there is hardly anyone doing rustproofing type of work. I could probably do it myself, but don't have the time or desire.

That looks great, been watching a few dry ice blasting videos and it looks like the way to go to clean anything, especially vehicle undercarrage.

Think someone here was wanting to remove the undercoating they did on a classic car, the video shows them cleaning off a 60's Chevy Wagons under carriage including the undercoating and zero damage to the metal or plastics.

Maybe when I retire I'll invest in a mobile blasting service.... put my son in law to work doing the jobs, he'd like that...

I priced out renting all the equipment and the amount of dry ice to do this before coating. Quite costly. Way more than what this cost me.
The cost was just not worth it. If it were a show truck or a full restoration maybe.
This was my grandfather’s truck so it’s just a piece to piddle around in and enjoy.

And this coating will last and prevent further rust for a very long time.

You wouldn't think of the South as being a "rust belt", but that generation of GM trucks (MY 1999-2006) kept me busy replacing the steel brake and fuel lines that rusted out. I had to refuse work on a few that had the frame fold in half. This is the only thing that kills them.

That looks great, Black! You'll be glad you made the effort 20 years from now when that thing is still going. Which reminds me...I need to replace the driver side floor pan in my 01 when it warms up. And egregore is right...I've already replaced all the brake lines.

Maybe if you start calling it patina, it would be nicer to you.

Yes both hard fuel and brake lines have been replaced along with the rear calipers.
I have the 2 piece rear dust shields waiting to be put in as well.

It has just over 100k miles so the 5.3 has plenty of life left.
We have owned this truck since new.

Looks great! My 2002 could use you driver door panel and dashboard! I can’t find them anywhere! This was when they were made well. Mine is exactly the same as yours including being a Z-71 except for being a 2002. I have about 160K miles on mine. Someone just recently tried to steal my taillights so now I have to find new screws.

This is the most recent picture I found of my truck when I pulled the oil pan to clean it out, replace the gasket, replace the oil level sensor, and the oil pickup tube o-ring. I was shocked at how good the oil pan was. I expected to find sludge in it. I have always used full synthetic and do regular oil and filter changes.

Try LMC for any parts you might need.

Thanks, I will check it out!

Another great product to kill rust is POR. If you use it wear gloves! It is very hard to remove. Good job on the truck!

I feel the same way...in southern NY, finding some place to do it for less than the cost of another car is unheard of
