    So,i did some homework on hamb,how to get rid of the factory tar on shoebox floor pans.
    Shoebox guys know how painful this crap can be,i havent wrestled with this issue much,because there wasnt much tar left on my floor pan ruins...
    Anyway,i found some answers for the tar issue.
    And i had to try it and it really works!
    I guess some of you guys know this trick,so nothing new to you.But i wanted to share this one with the guys who doesnt know it.
    So here it is:

    1.Pick up the crappiest air chisel bit you have

    2.Pick up about 2" wide steel plate

    3.Weld the steel plate to your crappy chisel bit(I made a notch to the plate,fitted the bit to the notch and welded it by tig.It should hold it)

    4.Make the sharp edges round,so they wont harm the floorpan metal when you are hammering the tar of.

    5.Beat the shit out of your floorpans...literally:D

    The non professional rally car builders, the ones that buy old Volvos and race them use Liquid Nitrogen to remove the tar etc. With protective clothing etc you blast the undercarriage and then wack it with a chipping hammer. It falls off like ice off the side of the car.

    Try "Dry Ice". Then a hammer for easy removal.

    We use a cheapo air putty knife from Northern Tool. It doesn't have the hard hit and stroke length of a air chisel.
    Where it's too thin to rattle off, we use a propane torch w/ a paint stripper nozzle.
    Once off, some old rags and a gallon of mineral sprits.. looks great!
    I took about 2- 5 gallon buckets of that crap off the underside of my 6T5 Hemi car..Took a day to do it. [On a roto.]

    Just use a soft flame from a propane torch. Warm the metal slightly and it will peal off easily with just a stiff putty knife, easy as pie. I've done several cars that way. After the bulk of it's off then soak a rag in kerosene and wipe it down to bare steel. Guaranteed to work!

    I used a 5" wire wheel on a hand held grinder for the big areas. It made quite a mess of my garage with tar flying everywhere...but id did come off easily and fast. Then to finish I wiped it down with kerosene.

    When I had mine I just thumped the floor with a hammer and the tar separated from the floor so easily I just peeled it off in large pieces. On my current OT project I was able to strip the front floors that way in 3 minutes for each side.

    Discovered when the master cylinder sprung a leak that the brake fluid turned the tar to ooze and just used a putty knife.
    Just happened that way.:)

    I had a '67 Mustang that I had about 10 gallons of tar and undercaotingto scrape off.

    I used a propane torch and 1 inch steel putty knife/scraper. Worked great, until I ran out of propane.

    Grabbed my heat gun and used that. Worked better!

    Just work slowly and heat and scrape as you go.

    Might work better if you wait till it gets COLD out (If it's not already in Finland???)

    I work for a rental company that rents Cold Jet dry ice blasting units. The unit uses dry ice pellets for a media. We had some ice left over from a rent so i brought the front clip from my 55 Chevy second series pickup to work and tried to remove all the under coating. I used about a hundred pounds of ice and removed the under coating down to the paint without damaging anything. They are too expensive to just rent for a job like this but you may find a blaster in your area that can handle the job. We demo'd the unit for the City of Denver on one of their tar trucks and same thing there. Removed the tar without damaging anything.

    I'm building a driver and not a show car I scrape and wire brush any LOOSE stuff but I'm afraid that I wont be able to do a job as well as the factory did 60 years ago. If I have to use an air chisel to get it off after 60 years it's on there good enough for me. I use rattle can undercoating mostly to clean it up for looks afterwards.
