Why am I doing this...

[beammmer]

Going with an Esty carpet install and down to the tarry crap. Is there a reason why I can't put the mat (dyna or raam) right over this stuff? Dry ice is a pain, heat is a gooier pain and neither gets rid of all the tar, it just never goes away.

Two days and only the rear floorboards have limited tar. And I'm worn out. The fronts appear much more difficult sections.

Is this "clean" enough? It was wiped with solvents, but it just never goes away.

Thanks, in pain,

Don

Don, I think the only reason for Saintly clean is to ensure the presence or lack of rust. If you are convinced of "no rust" i would slap the Dynomat on.

The dynomat will not care, the carpet will not care and I do not care. Who dat?

The only other thing to consider is painting the floor with some good primer or something to seal it.

Dat tar stuff is unbelievable. Would you put the Mat stuff right over the tar?

Sounds great to me.

No rust at all and it lasted 40 years, this week. If it lasts another 40, I think I'm good.

Coming down anytime soon?? Superbowl in three weeks, town will be fun.

I am currently doing the same job. I have to recommend - WD40 and #2 course steel wool - followed by shop rag paper towels.

WD40 is a nice solvent for the tar - it cleans up really well. If you want it to go a little faster - heat the tar with a heat gun before scrubbing with a WD40 sprayed piece of steel wool.

It is worth it. Get it clean before moving on.

I always wondered what the dry ice or heat gun is doing to the paint/undercoating under the car...

The humidity here the last two days was 100%, at least, while 75 outside. The underbody was sweating due the cold temps from the ice. I had a couple fans blowing hopefully drying as much as possible.

3M adhesive cleaner (not the spray kind as seen in the pic) works wonders. Pour it on top, let it sit for ten minutes and then just pull the pieces out.

Dry ice cleaning is the bomb but if you don't have a machine, it's $$$$

I broke up the dry ice and put it in a heavy duty plastic bag. Better contact that way. The tar came up pretty well. I used the 3M Tar and Adhesive Remover on the residue and it cleaned up very well. I threw a 100w drop light against the floor pan to help it soften a bit and while not the most pleasant job it cleaned up really well. I like the WD-40 idea. The 3M had best be used in an open space...what was I just saying?

Ahhh, I thought you were talking about dryice blasting. See my post in OT: http://www.bmw2002faq.com/component/option,com_forum/Itemid,50/page,viewtopic/t,380497/

A dry ice blaster would take care of that job in 30 minutes MAX.

If you're just going to lay dryice on it, I would buy pelletized dryice, the kind you use in a blasting machine:

Yes, Tito's has worked, but not as well on the floorboards.
