This post is along time overdue. Work and mountain biking season have teamed up to dispose of all of my time. We had a beautiful weekend and I just couldn’t resist spending half a day scraping sound-deadening material out of the inside of my bimmer.
What a horrible process. I started with the floors in the back of the car. That was best done by using the dry ice method. I had three bags of dry ice that I set on different spots on the floor. After they’d been there a few minutes, I moved one and chipped out the sound deadening material from under it. Then I’d move the next bag and chip out what was under it, and so on. I probably would have done better with just two bags of dry ice. Three was overkill.
The part of the car behind the back rest of the rear seat was easier and harder at the same time. The dry ice didn’t really help here. I just took the scraper and scraped it off. The stuff was still gooey, but it came of pretty cleanly. It left some adhesive film on the metal, but I should be able to get that off with some goof-off and elbow grease. It scraped off pretty easily. I got both rear sections of floor done and about 60% of the seat back area. I still need to do the part of the wheel wells that poke into the cabin.
I’m contemplating taking the sunroof framing out. I read the article in Grassroots Motorsports about their spec E30 build and they said it was pretty easy. There are a few spot welds and a bunch of glue to be removed. I looked at the 2002 and it is close to the same. There are metal tabs that come out from the corner of the roof to meet the sunroof frame.
My sunroof panel is currently glued in place with Permatex adhesive silicone sealant. There are a few guide screws that press up on the panel from the sunroof frame. They were mostly there to hold the panel in place while I glued the sunroof panel in place.
Eventually I’m going to weld something in place to cover that hole. Right now I’m going to leave it glued. When I get the body sand blasted, I’ll make a new panel and weld it in. GRM just took a sheet of steel and riveted it to the roof. I’d like something a little cleaner than that if I can.
I’m hoping to get some more time working on the car this afternoon. I know tomorrow I’ll have much of the afternoon to work on it. With two more days of work I should be able to get all of the sound deadening material out of the car. Since both passenger side floor panels are going to be replaced, that should not be too difficult.
I’ll have photos up tonight or tomorrow. Thanks for reading.
