Best Solvent to Remove Black Snot?
 

The PO used that black adhesive that stays sticky. Not sure what the actual name of it is.

Have tried IPA and acetone, neither of which work very well.

Any other suggestions?

Thanks.

Goo be gone?

Few years ago I was trying to remove some 10+ year old vinyl decals off the side of an enclosed trailer that spent life outside 24/7. I was successful in removing the vinyl with a heat gun, the glue remained.

I tried every chemical I had in my garage (acetone, lacquer thinner, rubbing alcohol of varying strengths, goo gone, 5 different de-greasers, gasoline, diesel......) nothing really put a dent in the adhesive left behind.

I called my friend at a vinyl sign shop, he came over with a bottle of this:

We sprayed it on full strength and it literally melted the adhesive away.

These work really well too:

Have you tried cussing?

WD-40? If this is in ref to the felt trim in the door-jam, I'd be super careful about anything screwing up the paint. I.e., acetone would have been a non-starter.

Contact adhesives that stay "sticky" often dissolve in petrol.

I think it's "dum dum" that you're dealing with..

One trick we use to remove it is to take new strip caulk, put some gloves on, and dab the new goop to the old goop. The old goop often times adheres perfectly to the new goop and will come off cleanly. Solvents won't work worth a darn. BTDT

This works well too.. Not so much for cleaning execution, but masterfully well for the necessity to maintain perspective that you are in fact 'winning'!

Seriously though Varsol should take it off.

Yeah, I think it is dum dum.

It's like the black caulk that's used to install windshields. Super sticky and never hardens.

This is the stuff:

Exactly right. Butyl tape, strip caulk, dum dum, etc... It's all miserable to work with and the same base chemistry. My suggestion will make it less painful, especially if you can find some amount of it that is partially solid.

Xylene

same
 

I use something called Paint prep, was made by 3m I think, anyway lots of solvents but xylene was the most prominent ingredient

XYLENE 😀

Ribbon sealer is another name for it.

I bet brake cleaner dissolves it - it does that rubbery undercoating stuff and Porsche's cosmoline coating.

The black stuff used to install windshields is a typically urethane. Talk to windshield installers and they just cut through it with a wire saw and add a fresh layer for the new glass.

In my experience, strip caulk and body seam putty get removed mechanically. They stay pliable in service for a reason. Meanwhile, when I find something in that service that's not pliable, it's often something like weatherstrip adhesive or black silicone caulk. Weatherstip adhesive comes off with acetone but it takes a long while after it's cured. I'd be tempted to try some spray gasket remover on a small place of what you have and see if that works. Acetone is really tough on paint and brain/nerve cells so it's down the list of things to use. Brake cleaners come in several formulations, almost all of which are tough on paint and brain cells. Use with caution, well ventilated areas, don't plan to have healthy children later, etc.
