Im at the body off frame stage on my 64, been under the body with a putty knife peeling off 46 years of junk ,STOPPED by HARBOR FIEGHT they had a air putty knife for 27 bucks bEST 27 $$ u will ever spend to get old undercoating off !!!! I know others may know this BUT for those of u who dont TRY IT spend the 27 bucks MAKES LIFE EASIER!!!!!!!!!!!!!!!!! Hope this helps somebody else thanks ray

Along the same lines,my local hardware store has a scraper attachment that fits into a sawzall. I picked one up with the same idea.

ray, i'm in the same boat on the issue.i'll soon be scraping the bottom of my 69 getting the under coating off. was the putty knife made of plastic or metal? thanks bill:thumbsup:

ALL medal came with 5 diff blade sizes WORKS LIKE A CHARM!!!!!!!!!!!!!!!!

Got a picture or can you send us guys a link to it?

found it!!! under $20 bucks to, gonna try it out this weekend.

ray, thanks for the info, i'll see what my local harbor freight store has. bill:thumbsup:

Got the box right here in my hand ,Its a PNEUMATIC SCAPER KIT item #95826 HMMMMM 20 bucks mine was 27 hmmmmmmmmmmm

I got mine for $19.99 and was best air tool bought in couple years!!!! This thing is not super fast like some might think but work it right with right compressor and does a GREAT JOB. I would recomm to anyone who has to remove undercoat. Brandon

I thought you were going to say that you found undercoating for $27 :p

Interesting tool This is the air scraper (http://www.harborfreight.com/cpi/ctaf/displayitem.taf?itemnumber=95826&Submit=Go)

I guess it's like a air chisel but with different blades? I can't help myself sometimes with harbor freight air tools. They're cheap, and for the rare occations I need them they work fine. Plus playing with a new air tool is always fun, and for $20 I am never let down ;)

If you use a a small torch ( bunson burner), heat the undercoating up and it scrapes off in a flash. Works great on wheel weels. I use a plumbers torch. Heat, scrape, the then wire brush it

sounds good i will be trying that in the up coming weeks:thumbsup:

I did 2 rear inner fenders in less then 40 mins with this and they where caked with undercoat! Oh you also don't have the bad smell like you do with a torch!!!!!!

Nice to read a thread where everyone is happy!!!:thumbsup:

I'm not! I spent 3 weeks on my back with a torch, mineral spirits and a scraper and now there is something easier! http://chatham-county-nc.com/bulletinboard/Smileys/default/headbang.gif

There's one in every crowd.:sad::D

If you put some laquer thinner in a spray mist bottle and apply it to the undercoating, it will become soft and easier to scrape off.. It might melt the plastic bottle too.

You can borrow mine on the next car, you need a wagon in the collection John.

Using a flame around the car for this job could lead to disaster.
Get youself an electric heat gun, you'll be much safer.

I tried the heat gun, a torch worked much better. Besides, my 10 year old had the heat gun and his own scraper :D .

I remember the statement from another post and said it to myself during the whole process "This is going to take a while and it is going to be sucky."

You guys all make this job WAY too difficult. My small angle grinder with a wire brush wheel took all the undercoating and paint off without a lot of fuss. You probably want to wear a dust mask but the job certainly goes a lot quicker this way and is a lot more safe (no heat or flames).
