Re: [MBZ] Permatex #2 cleaning

[Curley McLain via Mercedes]

MEK was essentially outlawed in the 80s.   MEKP is as close as you can 
get now, AFIK.  It works to make bonds in acrylic plastic sheet.


If you have access to chem stores at a major research  U, you might be 
able to get some.  However the one I used to get stuff from changed 
policy.  there are no cash sales.  Stuff only can be purchased on a U 
account, and those are heavily audited.  Even glass/plastic wares.

I haven't been able to get real MEK. I had a Por15 tank seal gone 
wrong which can supposedly be dissolved with MEK. It can't be 
dissolved with "MEK substitute"...

Wife used WD-40 to get labels off, and I seem to remember using it to get a 
paper gasket off. I would try whatever spray solvents I had on hand; Blaster, 
Aerokroil, brake cleaner, etc.

IIRC, (which I might not), either spray brake cleaner or B12 Chemtool did
the trick.

Here is the official spermatex  blurb:

The product can be removed from metal surfaces with isopropyl alcohol. 
If the sealant has been dried for a long time or at high temperatures, 
cover the sealant with alcohol and allow to soften overnight.


The problem is both acetone and alcohol evaporate quickly.  How do you 
soak it overnight unless you have a couple hundred gallons in a tub you 
can dunk the whole engine in?  Or spend a day dripping more alcohol onto 
a rag covering the $ hit?

a razor blade.  about 1/16th to 1/32 of a square inch at a time, if you 
get a good bite. Most of the time you don't get a good bite.  Still a

If you are scraping gasket material off of a cast iron surface, I've found
the Harbor Freight vibration saw [the one on sale for $15 ] with the
scraper blade that can be bought for it, is the best thing since canned
beer.

If the stuck gasket is on aluminum... proceed at your own caution, The 
tool

can get pretty aggressive and I fear damage to the surface would / could

On cast material.. .Bobs your uncle. I peeled a 40 yr old head gasket off

[MBZ] Permatex #2 cleaning

[Curley McLain via Mercedes]

Been scraping for hours on gaskets some genius glued down with permatex 
1 or 2.  Someone had a solvent for this #2.  OK Don I think?   What was 
that solvent?  I got the bulk of the gasket off the next one, but on 
nearly all the surface the gasket came apart rather than separate from 
the glue $ hit.  I have hours of scraping ahead to get to where a 
solvent might even work. I can'r imagine any solvent will dissolve 
the asbestos replacement stuff that makes up the bulk of the gasket.


Broke a good warner thin putty knife twice on this  $ hit.   Permatex 1 
and 2 suck big time.
