E30 (general beamer) under bonnet sound insulation removal

[Evo30 6]

Hi,

I got asked this by a few people and I saw a few people struggling to get these off.

Example below:

Very easy to removal and clean up. Most people with E30's exposed to a lot of weathering will have this stuff brittle and when touched, it crumbles. It is not heat insulation as it is not fire proof.

Anyway...

I recommend removing the bonnet before doing this, or just tarp over the engine.

What you need:

10mm wrench/ratchet (to remove bonnet) - well mine was 10mm....
Plastic scrapper
GLUE REMOVER! -- Ooomph from Bunnings works sweet - or anything with citrus.
Wax and grease remover
Rags
A MASK! at least for the first bit.

Frame 1-
1. Optional, I removed the bonnet. Ensure you mark its mounting.
2. Put mask on or harden up. Use plastic scrapper to make sure all foam is removed and glue is exposed. Water blaster is easiest.

Frame 2-
3. Spray Ooomph and walk away, for about 30 minutes! Make sure all exposed adhesive are drenched. I left it and ate dinner or something. The longer you leave it the better as long as it doesn't completely dry off.

Frame 3-
4. Use plastic scrapper to peel off the adhesive. This takes a while you may need to repeat process 3.
5. Once all is gone, use wax and grease to remove anything excess.

6. Spray Ooomph on to a clean new rag, go over the whole bonnet once more.
DONE! put bonnet back on. easy as.

Dads wasn't too bad, so we were got it off it chunks, then replaced it with brand new - less than $120 from memory.
