Ningen Kaijin Posted May 19, 2018 Share Posted May 19, 2018 Looking for suggestions and tools/parts waxes etc on how to restore the glass inside and out for N1 headlights on my R32 GT-R right now I have them completely disassembled anything helps Link to comment https://www.sau.com.au/forums/topic/474064-headlight-restoration-32-n1/ Share on other sites More sharing options...
Rusty Nuts Posted May 20, 2018 Share Posted May 20, 2018 I have cleaned the cloudy film off of mine with (believe it or not) Repellex personal insect repellant from Aldi. I used an old tee-shirt that didn't shed fibres. applied the Repellex to the cloth not the headlight, kept the cloth wet and worked fast, then used a baby oil soaked cloth to keep the surface moist. Wiped off oil then polished the lens with plastic polish. You must polish the lens often with car wax or they get cloudy again quickly. Did this in a cool shaded place if they are hot the cloth sticks. Strange but true!!

Rusty Nuts Posted May 20, 2018 Share Posted May 20, 2018 I am only guessing but the solvent in Repellex used as the propellent would be what removes the film, usually this is ethanol or propanol. Hope that helps. Link to comment https://www.sau.com.au/forums/topic/474064-headlight-restoration-32-n1/#findComment-7875971 Share on other sites More sharing options...
Rusty Nuts Posted May 20, 2018 Share Posted May 20, 2018 Apparently there is an Aldi in Osaka. Link to comment https://www.sau.com.au/forums/topic/474064-headlight-restoration-32-n1/#findComment-7875972 Share on other sites More sharing options...
emts Posted May 30, 2018 Share Posted May 30, 2018 32's are Glass I believe unlike your plastic ones. the plastic are a real PITA glass holds up much better but cost more so car builders moved to them. the 20yo headlights in my S14 are heaps better than the sub 10 yo ones in wife's Mazda. but back on topic What's wrong with the headlights themselves is it scratched sandblasted chipped?

Ningen Kaijin Posted June 5, 2018 Author Share Posted June 5, 2018 They seem to have gotten cloudy and can't see to well after I installed them wondering if there was anything I can do to fix them and yes they are glass has very small nicks in them but nothing too noticable Link to comment https://www.sau.com.au/forums/topic/474064-headlight-restoration-32-n1/#findComment-7877477 Share on other sites More sharing options...
emts Posted June 5, 2018 Share Posted June 5, 2018 glass will be much harder, you will still need to sand down then finish up with a Cerium Oxide glass polishing kit. basiclly work your way down in Sandpaper to very fine, then polish with the Cerium, it won't be quick or easy, but it is doable. best write up I could find: http://www.m5board.com/vbulletin/e39-m5-e52-z8-discussion/143993-diy-fog-light-sanding-refinishing-pics.html Link to comment https://www.sau.com.au/forums/topic/474064-headlight-restoration-32-n1/#findComment-7877498 Share on other sites More sharing options...
niZmO_Man Posted June 6, 2018 Share Posted June 6, 2018 Did the glass have 'night shade' sprayed onto it or something? You can bake the headlight apart and clean up the glass.

There are a couple of threads for retrofitting, but I'll create a thread on how to take headlights apart... Once I become un-lazy.

GTSBoy Posted June 6, 2018 Share Posted June 6, 2018 99% of R32 headlights are perfectly clear. Being glass, as mentioned above, they never get cloudy.

GTSBoy Posted July 1, 2019 Share Posted July 1, 2019 Sandblasting is the only way that glass lenses get "cloudy". Polishing glass is a different kettle of fish to trying to get rid of UV damaged polycarbonate.

niZmO_Man Posted July 1, 2019 Share Posted July 1, 2019 I'm pretty sure the picture has nightshade or some sort of paint/plastic over it. R32 glass is pretty robust.

GTSBoy Posted July 1, 2019 Share Posted July 1, 2019 Wow. I posted in response to a slightly inane followup and that post is gone, leaving mine sitting there straight after my previous post. Weird. I am prompted to ask something.....are the N1 lenses perhaps plastic, not glass? You know, for lightness?

niZmO_Man Posted July 2, 2019 Share Posted July 2, 2019 I doubt it, it's from 1989 CA18S R32s. I don't think they switched to plastic until the R33 era (which means S13, Cefiro etc are all glass?).
