Dashpad started fading and bubbling recently after having refinished it about 10 years ago...no problem since last time it went well. I took it out once again and in the middle of scraping the old stuff off - successfully I might add - I stand up to take a break and the scraper I had on my lap fell off...DOH - of course it had to hit the speaker holes area and you guessed it...
I now had a nice hole in a perfect dash pad...see pics. (Note, this was mid paint removal so the surface looks horrible - don't mind that)

The bubbling here is from a heat gun...it worked awesome to get the old stuff off...it bubbled nicely then I just scraped it off...

I wasn't sure how I was going to fix this...just repair that section or cut out the entire area and go from there. First, I re-created the "holes" on the computer to cut out of vinyl as template...I made one out of metal and a few "tests" out of plastic where I replicated the damaged area. (Yes I center punched and drilled all 147 holes several times lol)

I tried fiberglass, Mighty Putty and some epoxy gel stuff. The winner ended up being, believe it or not, the Mighty Putty...lol. The epoxy gel stuff was strong but a bit too pliable for drilling. The fiberglass was awesome but the test area got messed up when I tried to sand it. The test plastic didn't really sand well (my fault) so I decided I'd need to re-test that method. In the meantime, the Mighty Putty test had cured so I started working with it and ended up really liking the way it turned out so I rolled with it.
This is the repaired area from the bottom of the dash...you'll see 2 areas - the smaller area got damaged in the process too...lol. I had a backer piece of plastic on the other side so the putty didn't just fall through. It protruded just enough to take 2 seconds to sand smooth...there was no seam either.

The area after primer...

The area after final painting...

...AND back in the car...(hard to get a good shot in the garage

Overall I'm super happy with the way it turned out - way better than $100+ for a new (used) dash pad.
