2015 Lacrosse Drain Holes?

[300sflyer]

Hi folks,

I am wondering what the purpose is of these plugs? I am about to get the car rustproofed with Krown, and wonder if these plugs should be removed first?

Thanks for your replys!

They are part of the manufacturing process of the rail and are then plugged at the factory. Krown should know whether their process requires removal and reinstallation.

The rust-proofing process, they drill their own holes and plug but agree may use some existing. I’d be concerned about developed rust that will be covered over? Inside frame and all hollows. Right at jacking point is a drain hole, those should be maintained open, others in rails also.

I never got the whole rustproofing thing, I'd rather invest my money in frequent car washes in the Winter.

I tend to be believe in both, especially if you plan to keep a vehicle for 5 years or more. Krown or Rust Check definately helps keep vehicle cancer to a minimum.

Had Krown applied yesterday. They pulled all of the plugs and sprayed inside the holes, which I was glad to see.

Thought Rustproofing ( Ziebart & Rusty Jones ) went the way of the Rotary Phone & Leaded Gasoline.

The Concept of drilling into steel, Creating holes, and Spraying a wet tar based Goop in an attempt to prevent an ongoing earth / time / air / natural oxidation process is just nuts.

Snake Oil - Aftermarket Post Sale Dealership Profiteering whilst actually creating entry points for the rusting process to more rapidly happen than normal.

Don't get me going on Paint Protection, Fabric Sheild, and VIN Etching...

Why Do Cars No Longer Need Aftermarket Rustproofing? | Web2Carz Never gave it much thought as keeper gets put up every winter. What kills cars in ME anyways, had one car and hole rusted through top of gas tank, rear quarters repaired but that was under their rustproof warranty, so forth and such.

Back when they actually oiled down dirt roads we would squirt used oil in all the cavities we could find. Early ‘60’s recycling I guess, hmm.... Oil Spray Rustproofing

To each his own....

All the vehicles I have owned for the last 20 years or so, I have had sprayed with Krown or Rust Check on an annual basis. IMO it has made a big difference. No body panels rusting out from the inside on any of them. When I eventually decide to sell them, I get top dollar.

My other current vehicle is a 2008 F350, that looks almost as good the day it rolled out of the factory. My neighbours 2011 F250 that has never been rustproofed, and has about half the mileage mine does, looks like a much older truck, due to the rear fenders starting to rot out. That's proof enough for me.
