This stuff is driving me nuts. I can't afford to blast so i have been scraping this stuff off after hitting it with the heat gun. I just have the wheel wells left to go but I am using my elbow grease up pretty fast...
Sorry just ranting

hang in there, the end result will be worth it

 

Yea, that crap sucks to get off. Are you putting new undercoating on or painting it?

 

I plan on painting it. por 15 first. does undercoating provide some sort of sound proofing? it was all over the car. inside the fenders outside the engine compartmen, all over the undrcarriage

 

I used a cupped wire wheel (coarse twisted wire) on a 4 1/2" grinder. I did the whole underside of my car and it worked great. It is pretty fast and easy. Only problem is that it throws that crap around pretty good. I worea paint respirator and eye protection. I got covered in the residue, but it washed off.

 

I tried a wire wheel on my drill but it didn't work very well. i didn't get down to metal. I might try it on my grinder though...

 

Same thing on mine a 6" wire wheel on a grinder.

 

Id be careful using a twisted wire wheel on sheetmetal...

And rubberized undercoating does offer sound deadening, or, atleast the cans say so...

 

With the 4 1/2" grinder and the twisted cupped wire wheel I could control it well enough that I left the paint where I wanted and took it off where I wanted.

 

Do I need to put the undercoating on for sound? i plan on using the sound deadening mats on the inside under the carpet
