A buddy of mine used one of these when he stripped his Chevelle. It's a little pricey, but worked like a charm. He says it was worth every penny. Best part is, when I'm ready I can borrow it as long as I buy a new head for it.


high $ Snap On tool

I just looked at the sanding tool you were talking about and these are priced about the same. Your sander could obviously be used for other things, the Snap On tool is a uni-tasker.

$5.99 cans of paint stripper and double sided razor blades and 1 1/2 scrapper with one side slightly grounded down works good. Do sections at a time. Hell with the torch and keeping it moving scheme........I can see potential drama in that.

I used a needle scaler on lots of areas.
It worked great.

Leave it on. If its that hard to get off its doing a good job of protecting whats under it. Whatever you put back on may not be as good.

Okay, I give up, what is a needle scaler? In answer to leaving it on I'm running fenderwells so the area where the coating is will get hot. I'm leaving the coating in the upper fender well alone.

It would not be my choice... I still prefer using a torch to soften undercoat .and a wide scraper to remove it...

Use proper PP. Personal protection. My welder ended up in the emergency room with an awful rash when grinding the undercoating off on a hot day. Baaaad rash. The subframe connectors are great though...

You can get needle scalers at harbour freight or Princess Auto up here in Canada,They are cheap and did a great job on my car.
After the scaler I had very little to clean.

I'm using a heat gun but a wide scraper as well. Mine seems to come off pretty easy, so far. While I'm on this subject and not to deviate from the OP but here's a question related to this:

What to put/do to the metal after removing the undercoating? I would think you need to do something soon to prevent anything happening to the metal. In my case, it could be a while to take it to a body shop(if that's the process)

If anyone is close to me, and your car is on a rotissierie. I will remove everything off the bottem of your car except for the paint in about 4 hours.You could bring the car to me or I could come to you.No scrape marks or gouges and no open flame used. PM me for the cost and availability.

Normally the metal would be media blasted and then immediately primed and painted.

I used a needle scaler also but I can see where it might not work with other cars. I had the black undercoating on the car(barracuda) that was hardened and it came off fine with a needle scaler. But, the 69 Superbee has the snot colored stuff on it that seems more gooey. If anyone chooses to use the needle scaler, spend the money and get the Ingersol Rand unit from Northern Tools. I used the one from Harbor freight and it lasted all of about 5 hours and the local store told me to pound sand on an exchange, it was a factory warranty. The two units look identical but the IR unit has lasted.

By the way, if anyone is near Challenger1, take him up on his offer for removal and media blasting. Both jobs are time consuming and well worth the money spent to have others do it better and faster.

I just might do that Challenger 1. I've seen what you have done to your car(s) and I'm impressed. It would be worth it to me to bring it to you or come up with other arrangements
