Did the headliner this weekend. Took about 20 hours total, which seems like a lot; and I was not taking breaks. I was so tired last night, not even sure why I was so sore!
After removing the trim pieces I immediately prepared them for a color coat Friday night. I only did select items, but was pretty time consuming. 3 coats of adhesion promoter / 5 minutes between coats, then 4 coats of color / 15 minutes between coats. I used SEM products.
Saturday morning I pulled out the headliner. The wire loom to the overheads on the drivers side, and the washer fluid line on passenger side were glued to the headliner. I peeled them off before getting it out.
Then pulled out sunroof cover. After pulling off fabric found the foam had turned to a sticky goo. Scraped it off with a razor blade, then used paint remover with a scraper to remove rest. Put on fabric and sound deadening and set aside.
Before I started with anything else, I added sound deadening to the ceiling.
I pulled the fabric off the foam on the headliner. The foam was in great shape so I decided to go over it with the new fabric. I sprayed 3M super 77 on the foam and the fabric as I went. My wife and daughter helped me lay it down. They held the roll as I sprayed and smoothed it out. I waited about 2 hours and trimmed it out.
Going back in took about 4 hours today. I used gorilla tape to reattach the harness and washer hose to the top of the headliner. I had some sound deadening left, so put it on the inside of interior plastics strategicly. Put all the trim back on, and tucked all the fabric back in.
It’s definitely quieter, and I still plan on doing more soundproofing to the doors and floor when I put the system in.
