Used this material today to do my dads dew wipes. Worked perfectly. Pulled his old ones, ground rivets off hardware (felts and mirror mount), cut to length and drilled to match and riveted hardware onto new piece. This dew wipe material is not flocked the same, but is completely rubber coated. I know the Fiero Store is out of them with a wait time of months. I used theirs on my car in January and they worked fine. I didn't see any of the issues pointed out in a review on here. My Father bought an 87 GT a few weeks ago and these were sorely needed before Summer gets here. If you want to get this done and have a cut off tool, a drill and a rivet gun this will work fine.
We did not nave materials to re finish the felts, but they weren't terrible -so we just cleaned them up.
I wanted to post the link to the material that worked so well for us. It is nearly an exact match and worked great.
I don't want to minimize the effort required. It is well discussed on here the wrestling match the access to the dew wipe screws can be. Once you find the instructions on here and do one, it becomes way less intimidating. Once off - take your time. Measure and mark the holes carefully and make sure that your new rivet heads are as flush as you can get them. The time we invested was well worth the effort to have these done without waiting months to get them.
