Easiest Way to Remove Underbody Coating

In this video I show you two ways to remove underbody coating and which I think is the best and least time consuming, way. 1. Heat gun and scraper. 2. Air scraper/wirewheel. No matter which way you do it, this process is going to be messy and take some time. Obviously it would be best if you could sand blast or media blast, but hey, your watching this video because you didn't chose one of those options. **Remember this is just my opinion with what I read on the forums and what I had available. So here is what I think the best and easiest way to remove this old crappy underbody coating.

After countless hours with a discs/etc I've found that using a wire wheel with very short wires that won't "lay down" works very well. With decent pressure it destroys everything in it's path and will take things down to bare metal instantly. So quickly that the underbody coating comes off as dust. It won't heat up and/or smear around. No acids/strippers, goo, multiple layers to remove. Cheers

Your videos helping me get motivated to continue with my project 240z. Thanks!

Eastwood sells a product undercoat removal its made with citra safe, coats in a foam, let it  soak, scrapes off easy with a 45 deg scraper,

I used a harbor freight multi tool with scraper blades and once the rubberized came off. I used a twisted wire cup brush. Worked like a charm

[markblades]

Decided to take mine off in the end, used a vibrating multi tool in the end with a thin chisel blade on, was a lot easier than I thought, your videos are a great source of info, thanks for your efforts shooting them 👍

[markblades]

Great video Mate, superb info, I'm just debating if I take mine off

[remedyz]

I used a blowtorch for it. Once most of it is off, used a knotted wire wheel for the rest.

[whyiterp]

ya can use a torch its quicker just move the flame around kinda quickly in 1' x 1" area for a about minute and then scrape whats left comes off with acetone and steel wool no damage to metal comes super clean and ready fro a 1 or 2k primer/topcoat

Good vid, I gotta do my jeep ! Thanks!

Great work. Do you recommend undercoating? I saw some videos on YouTube suggesting undercoating is not beneficial to resist rust and might trap moisture? Please suggest?

Gasoline melts undercoating. Soak it down, then scrap or scrub with a copper scrub pad then wipe up the goo with paper towels. Fairly fast and a ton cheaper than Goo-gone.

[tthams]

Oven cleaner work great! Spray, let it sit, scrapes off clean

[SupramanTRD]

Thank you for the video. I'm removing the undercoating from my evo, so I can sandblast and restore the car

[MindDezign]

you need a thicker putty knife then that one you have a heavy duty version of that then just scape I found that the old under coat on Z cars will just scrape off with a heavy duty sharp and keep it sharp scraper. Heat can just make it messy but in some areas just may be what you need. good video keep that car progressing. I almost have both of my Z cars floor and chassis completely welded up so I'm happy to be able to soon turn it right side up for good ha!

I just got done doing this a couple weeks ago on my project.  For people who don't have a decent compressor to keep working with an air chisel, you can use a multitool with a scraper blade.  I mostly used the propane torch and a hand held scraper.  For the residue, I heated those up with the torch before hitting it with the wire wheel.  It took me a whole week to remove the whole underside of the car and inside the wheelwells.  It's not very fun at all.

best way is a pneumatic needle scaler. Harbor Freight sells one for $55. Low cost and it gets into the tight spots very well.

that air chisel works a treat! I've done all the interior sound deadening in my car, now i need to do the under body sealer, and i'm not really looking forward to it, especially that its around 47°C here in Sydney now! (that's 117°F to you!)

[dcarspeed]

Amazing video hands down! Thank you! What did you coat it with after stripping it all?

[elijahperez]

I've never seen any kind of blasting remove any resin like substance. I have seen people use dry ice on the interior resin, sound deadening stuff though. It flaked off very easy once frozen. I've seen it on tv but never tried yet.. I've been wanting to give it a shot

[topwater]

power always helps lol... bout the way I do it I used map gas then wire but taking it off cold is a new idee!! fosho!! ..check ya later buddy ..toppy
