“I’m sure this would bore you”
Me who would watch every last second of the time lapse: 👁👄👁

In going through this process, my first advice is don't go straight at it with a strip disc. Get your hands on an air scraper. I used the scraper to take the largest chunks of the undercoating off. Once those were off I then would hit it with the strip disc. This extra step saves so much time.

I ain't never seen a hard work like that
Keep up 👆

Love this! Looks great, makes me want to get my restoration finished 🤣

[chse]

[Bearclaw]

You're living my dream, I'm excited to see the progress!

Quote of the episode "I don't know why I'm using an angle grinder when I have a sandblaster"! I wish you had taken that approach with the whole

Editing is looking more and more solid as the playlist goes on. Great work, thank you.

When I recently stripped the bottom of my car I used a firm putty knife and razorblades in a holder to scrape off the undercoating. Then I degreased it. Then I followed up with an electric palm sander with 60-80 grit. Took a long time but I don't have a big enough compressor to run air tools. Then I used a Dremel with the tapered cone sanding rolls. 80-100 grit. Pretty expensive but they get into the nooks and crannys. I love those things. Great video. Looks good!

I was skeptical of your work but it came out very nice!!!

Your content is some of the best I have seen in the auto restoration arena. Great job. I get nervous before I start any big project without knowing a good deal about what to expect. very very helpful!

Question is this: in your planning phase, did you consider a paint coating of some noise/heat control material? I'm working on a 1963 Chevy Corvair, and I wondering if I should look at using something like that over the rust por-13 coats or whatever. what do you think? Corvairs are loud, stinky, and the air cooled rear engine gets pretty hot...

My 260 had the same cracks, a lot of torque on that area from the rear axle !

Fun fact: Datsun/Nissan didn't undercoat the cars in 70's for the purpose of rust prevention. They did it for sound-proofing. Best to leave it on there in the areas where it's still good (as you are doing) and only remove the stuff where rusty repairs may be needed.

This is really next level work. I just got a jeep so I’m learning how to treat and keep rust off that sucker. Thanks for the video.

It's been a while since I screwed around with undercoating, but my recollection is that like paint, undercoating lasts longer if the resulting coating is thicker. The undercoating you are saying is good enough to leave on, is very thick. That thickness is partially why it lasted. The thickness of the undercoating you are ending with looks to be less than 1/16 inch thick. The thicker the coating, the more it dampens vibrations and road noise, and can endure abrasions (rocks hitting the bottom of the car, etc.)...

I gotta say this before and after was insane to see. Keep it up

[jackhudson]

For the repairs that you did to the floorboard, why did you decide not to sand down the welds to smooth them out before spraying the undercoating ? Enjoying the videos ! Thanks.

[michaelsaxonson]

I think the way to go on this would either be a sand blaster or use a pressure washer to clean and then spot treat the areas where the undercoating has come off or rusted

[Asdf]

Thanks for the video! I started it on my own and holy f the angle grinding takes longer than you expect. It’s like every time I look I find more spots I missed.

I just have the fenders and hard to reach spots and then I should be close to finishing 🤣
