October 4, 201311 yr comment_432977 If it is acrylic then it will polish itself nice, shiny and scratch free with the heat if not it might just melt..Will be watching this thread..No need for a heat gun. I used the Meguiars #17 and a buffing wheel I bought at Harbor Freight. They also sell a polishing compound stick for plastic that will make the plastic lenses shine like new. I did this for all of my tail lamps and markers too.Go here: 8" Benchtop Buffer. Here is a coupon: 25% Off Coupon - or - use code 43280812 at checkout. Brings the price to $50.Although the results are impeccable, you have to be very careful when using this buffing wheel. There where a couple of times the lens would get caught and fly across the room. I have to say that it really made the tail lamps look like brand new. Outstanding Results.

October 4, 201311 yr comment_432987 I have tried to do some plastic buffing with buffers that run at those speeds and have found it very easy to melt the plastic. I would like to get a 2 speed buffing wheel like Eastwood sells but the initial investment is getting in the way. I guess the main point is anything above 2000 rpms will melt the plastic quickly use caution...Charles Link to comment https://www.classiczcars.com/forums/topic/47535-cleaning-and-restoring-guage-faces/?&page=2#findComment-432987 Share on other sites More sharing options...

October 12, 201311 yr comment_433553 I did some googling on this and didn't come up with anything.

July 24, 20159 yr comment_474436 I recently did this on my early 260z and attempted to fix the clock but ultimately bought a quartz replacement. From my experience:1. Dont bother with LED's. Light is extremely complicated and because these gauges are indirectly lighted the LED's just dont look right2. Theres a PDF file floating around here about white face gauges, print yourself a set but don't plan on replacing your gauge face.3. The insides of the gauges are in fact painted white to reflect the light from the bulbs around the gauge face4. Disassemble the gauges and polish the lenses with a plastic polish as mentioned above. I did mine by hand5. The gauge bezels can be spray painted with black vinyl spray paint. This paint is super thin so you dont loose the existing texture on the bezels. If you cut out the white gauge face template its an exact cover for the lenses for masking while you paint. I didnt separate the lenses from the bezel but they werent bad. https://sites.google.com/a/thecomputerrehab.com/260z/Interior/dash-refresh6. I did a bunch of research on bulb replacement and ultimately used these which work great: #3893 MINIATURE BULB BA9S BASE, T2 3/4 12V .333A, 3893,#3893,#3893 MINIATURE LAMP,#3893 MINIATURE,#3893 BULB, #3893 LAMP, #3893 INDICATOR, EIKO#40659What kind of spray paint can i use on the speedometer gauge? Black Flat can spray? Is there an specific Brand? Should i use sandpaper to peel the inners before spraying?

Â If you are referring to the bezel I recommend a paint designed for vinyl, it worked very well for me Link to comment https://www.classiczcars.com/forums/topic/47535-cleaning-and-restoring-guage-faces/?&page=2#findComment-474551 Share on other sites More sharing options...

July 28, 20159 yr comment_474698 I bought the paint at the auto parts store.  You want to be careful with sanding because the surface has a slight texture to it that you could accidentally remove.  I rubbed my parts with a scotch-brite pad extremely gently, wiped them down and applied a light coat of paint. Link to comment https://www.classiczcars.com/forums/topic/47535-cleaning-and-restoring-guage-faces/?&page=2#findComment-474698 Share on other sites More sharing options...
