ok so i had the same problem that faces pretty much every crx owner who still has the original headlights: faded/pitted/just plain deteriorated reflective chrome inside of the housing resulting in poor headlight performance..
after doing alot of research on this forum and others i was pretty depressed at the probable conclusion that my only options were to order new ones, get mine restored by a professional company (which would cost more than brand new ones), retro fit some (which would be awsome but a litte to much for me right now) or buy those crappy halo projectors that arent even all that good and look like doo-doo IMO...
then my gears started turning and i figured a way to restore the headlights myself (as any good honda/crx owner should)
here is a somewhat write-up of how i did it and this is my FIRST "write up" so it may not be up to par with others but its a shot...
Supplies:
2 worn out crx headlamps
1 oven
1 hammer
1 flat head screwdriver
1 can (or bottle) of glass cleaner (I used Rain-X Foaming Spray)
2 tubes of Permatex Ultra-Grey RTV
1 can of Eagle One Never-Dull Wadding Polish (safe for both chrome and aluminum making it ideal)
1 roll of Nashua HVAC tape (i'm not sure if this comes in different grades but the roll i had seemed pretty industrial)
and lastly some razor blades and I used and Exacto Knife as well
To start you have to get the headlamp off of the car which means you must take off the front bumper, here is a quick thread on bumper removal if someone needs it: https://crxcommunity.com/viewtopic.php?f=3&t=22827
once you have the headlamp out and separated from the black bracket you have to BAKE the entire headlamp for about 3-5 mins at 400 deg so that you can separate the glass from the plastic housing. Be sure to remove the c-shaped clamps that hold the glass to the housing before baking it. The clamps can be easily removed with a flat head and a hammer by lining up the flat head (perpendicular) on the side of the clamp and tapping it with the hammer to slide them off. This is what mine looked like at this point:
as you can see they were pretty bad off
Now that you have the glass separated from the housing you will want to clean off all of the old sealant from both the glass and the housing, this is where the razor blades and Exacto knife come into play. this is a tedious process but should be done well to promote a good seal in the end; here is a couple pics of my glass and housing after getting all the old sealant off; also this is a good time to go ahead and remove the focus box that is mounted inside the housing by two screws:
Now that you have the housings and the glass clean and clear of the old sealant you can begin the actual "restoration" process:
This is where the HVAC tape comes into play. This tape made to withstand and remain adheasive in both high and low temps and it has the quality of being very reflective, which is needed. Take the aluminum HVAC tape and start off with some small strips (2-3/3-4 inches) and sit and trim and cut panels to re-cover the interior of the housing where all the chrome is dying. Just take your time and make sure that you lay every piece as smooth as possible, my finger tips felt bruised afterwards from pushing down so hard to ensure the tape laid flat.
Once you have the interior surfaces completely covered with the aluminum tape you can go ahead and polish. Now i selected a polish that was safe for both chrome and aluminum because I wasnt sure if i wanted to cover the entire surface or just the badly worn areas and leave the sections of chrome that were still good alone, so i wanted to have a polish that was safe for both materials; even though i ended up just entirely covering the interior surface of the housing.
So here are some pics of the interior housing after polishing:
as you can see after a good polish the aluminum is pretty much as reflective as the original chrome
after polishing the aluminum its time to go ahead a reassemble to headlamp. I used the Gray-RTV because i wanted to try and stay as close to OEM with the look, and it can withstand some pretty high temps also.
First off, make sure that your glass (both sides) and housing (inside) are nice and clean and you have re-mounted the focus boxes on the inside of the housing. I laid a pretty fat bead along the entire perimeter of the housing filling the "channel" or groove about half way with the sealant then placed the glass onto the housing and applied the metal c-shaped clamps in a criss-crossing fashion using the same method to put them back on as i did to remove them, by tapping them into place with a hammer and flat head.
Here are some pics of the final product:
And here are some pics of them on at night:
like i said this is my first ever write-up and i just hope it will help out anybody looking to fix up their headlights a little bit. and comments or questions are welcome
thanks for looking!
p.s. no, those arent HIDs.. just plane jane bulbs
