using acid to remove gooey stuff?

[Obin Robinson]

update:

the 924 interior project is coming along GREAT! i have so far stripped ALL of the acoustic insulation from the middle of the car back to the rear bumper. the only insulation i did NOT strip is the one directly above the fuel tank. i am taking lots of pictures of my progress and hopefully by saturday night, the 924 interior will be done, and the car will be ready to have it's seats reinstalled!

but...

a friend suggested that i make a mixture of acid and water and lightly apply it with a sponge to remove all the residue from the adhesive used to glue down the tarpaper-like soundproofing. i am going to do this, but i just wanted to check to see if anyone knows of something else that may remove all the gooey residue even faster. i've tried goo-gone and it works great to clean up the little bits, but it can't mount a direct assault on the majority of the icky stuff.

the interior of the car is getting painted satin colour. so far it looks awesome! i've removed about 30 lbs of insulation and the car really isn't much louder on the inside. i am going to weigh all the stuff that is removed from the car so you guys can get a good idea of how much weight you will save.

you know, with all the insides gutted... i think i might just order a roll cage sooner or later

so, to get back to the original point... other than acid, what can i use to remove the gooey stuff (i also tried bug and tar remover).

thanks!

A straight line is the most BORING distance between two points.

Try some mineral spirits. It loosens up adhesive really well. WD-40 works too, but if you don't get rid of the residue from the WD-40, the paint won't stick.

Mineral spirits will also take tar off of the paint too. Just don't use a lot, and wash it off after you get the tar off.

Good Luck!

Hi Obin hey whats with the acid I would not use any type of acid on the car as it could eat into the factory coating and cause mass scale paint lifting.. anyway that said most adhesives are made to be remover with hydrocarbon type chemicals if you have a lot of sticky stuff to remove try a lil bit of kerosene wipe it on then let it soak then wipe it off after this you will need to use wax and grease remover to clean off any residue of any chemical you choose to use then use a scotchbrite pad to score the surface so it will take paint .
The only thing that you might use the acid stuff for is remove old rusty surface or something like that otherwise stay away from it it will sit in the car and cause the seams and other nooks and crannies to eventually start to corrode..... I hope this helps.good luck with your restoration.....Stan

I dont think acid will do anything to remove the tar, the tar is probaly a base and will just neutralize the acid, I would try paint thinner.

thanks for the info so far!

well, i hacked away at it with EVERYTHING and that stuff is ON there to STAY. literally, i think the only sure-fire way to get it off is to use a metal grinder. i got 99% of the stuff out of there and it looks good enough. the stuff that is under the seats and not visible was just primed and painted over.

now some more intersting news. i have filled a garbage bag with all the insulation and soundproofing crap that was in the car. i think it's about 50lbs so far. this is great! between the missing back seats, no soundproofing, and no carpets, i think that the car will be a much better performer. the downside is that it will be a bit louder on the interior, and it is no longer a practical car. i am going to rewire the electrical system to the rear of the car. any idea where i can get that colour coded wire like what Porsche used (blue/white, red/green, etc)

thanks!
