Hood Insulation Removal and Insulation

[BillWilliams]

The old hood insulation I had on the touring was not BMW original and the three pieces did not match.

So I ordered new stuff and took the old stuff off.

To remove the old stuff, I "picked" the insulation off with my fingers, one pick at a time. Then when I had all of the foam that I could pick off, I sprayed 3M General Purpose Adhesive Cleaner on with an old spray bottle. Let it set, then scraped it off with one of those plastic Bondo applicators. This took several applications. Watch the fumes, they can do crazy stuff to you.

Then I wiped the metal down a bit with a rag moistened with the 3M General Purpose Adhesive Cleaner. A dampened rag with the 3M General Purpose Adhesive Cleaner, was handy to get the adhesive buggers off of my hands and scraper. The remover must have a bit of oil in it that causes the removed adhesive just roll off of hands and tools.

I then cleaned the surface with an all purpose cleaner - Fantastic, Orange stuff, etc.

The new stuff is the right composition but not the right size. Take the larger rectangular piece (15"x 19") and lay it on the triangular piece and cut it to the same size. You need the smaller rectangular piece (13"x 19") and two of the larger rectangular pieces (15"x 19") to do the hood. Or some report that their cars had two of the smaller pieces and one larger piece, you decide.

Line up and apply carefully, you get one chance.

Bill - your left piece appears off by 3 degrees and your right one is catywompas 2.5 mm.

Don't mind me - I'm just jealous because Celeste still wears her adhesive residue from some old pads.

Nice work and addition to the construction zone.

This one thing I was scored off on at Oktoberfest for the originality award.

The judges said my middle piece was off "just a bit" but I can not get them to tell me what "just a bit" is and which way to move it "just a bit". So I took my best shot at "just a bit".

I fixed the other thing they did not like. I had the wrong shift boot.

This post is really helpful - am stripping off the very nasty old insulation from the hood of my "73 2002 - lots of old and stubborn adhesive. Covering the engine as shown is definitely important! Used up one whole spray can of 3M adhesive remover and figure I need at least one more - can't find the one pictured, which looks better. Ordered a replacement set of pads that looks just like the one pictured. Good to see how it's done!

easier approach....

mark location and then remove the 8 bolts that hold the hood on. remove hood. lay it belly up on padding on ground. clean away! much better position to work in and eliminates getting any chemicals on rest of car. you can even use a hose to help. ez.

some folks appear scared to remove the hood because of the "mystery" of how to align it back on. if you just mark the bolt location accurately when you take it off, putting it back on is not a big deal.

Thanks for this post. I couldn't find the 3M stuff so I got the Goof Off Professional Strength Remover and it works great.

What type of adhesive is recommended for securing the new insulation pads?  Thanks
