how to remove clear plastic from instrument cluster
I want to refinish the interior of the from portion of the instrument cluster, and wanted to know the best method to remove the clear plastic front from the rest of the shell. On a related front, the gauges are going to North Hollywood Speedometer to be refinished - would they also do the interior of the housing? If so, this would be a moot point.

Is the plastic lens scratched ? Is this why you wish to remove it ?
If it is, there is a plastic refinishing polish sold which will clean up scratches and make the clear plastic look like new. It is sold in Motorcycle shops and some finer sports car dealerships parts counters.
Or you could check Amazon or search eBay for a seller. I believe I have seen products sold by Simichrome, Meguiars, P21S, and Griots Garage that will do the job. ( the tube I have, I bought nearly 20 years ago and do not remember what brand it is but am thinking it was P21S and sold over the Porsche dealership's parts counter. )

Easy to do yourself. Most use a small utility knife in between the plastic clear lens and the black plastic housing. Go slow and it’ll come off eventually. Then clean the black plastic as well as you can and shoot it with black rattle can.

Thanks! I always feel uneasy about these type of projects because if I break it, the new part is insanely expensive.

You don't say for sure, but this has to be a later car, right?
The 928 has a very similar cluster.
I took mine apart & cleaned it up. The plexi is glued to the 'body' of the cluster. But the glue isn't a continuous bead. And the glue gets old and brittle.
I used a sharpened putty knife. I could get it in a spot with no glue, then twist it gently to break the glue loose. Slide it over until it stops, then twist some more.
Slowly and gently were the key. No more force than is necessary to crack the glue loose. Take your time.
The really uncomfortable part about the process is that the glue cracking loose sounds a lot like plexi or plastic breaking.
I had several 'oh crap' moments, but they were all false alarms.

ditto to what rob-o said. Mine came apart when I was removing my cluster to fix the odometer gear and replace instrument lights. Its a glue adhesive thats probably pretty old and easy to separate at this point.

Got things pulled apart finally. It was slow going, and it did put a couple of cracks in the plexiglass, but not in the field of vision. New question is whether people have put reflective tape on both sides of light tunnels? My temptation is to do that so it will have maximum reflectivity.
