355 Muffle heat shield repair

While doing a little maintenance on my 355 I discovered that the muffler heat shield was damaged. Apparently the muffler had become dislodged and was rubbing against it wearing through the aluminum foil and buring off the resin in the shield substrate leaving only the glass fibers is spots.

After checking the price on a new shield ($1000) I decided I would repair rather than replace. Using glass mat and resin I covered the worn areas and then painted with aluminum paint.

After a little research I found some suitable heat shield material from Design Enginering Inc. (DEI). 10 mil aluminum bonded to a fiber glass heat mat with high temperature adhesive backing. The finished shied is shown below with old covering. Total cost, about $100.

Thanks Elliot. Admittedly, looking at your car has been a motivating factor for me. This all started when I decided to repair and refinish all the under trays on my car.
