Polishing or replacing scuffed headlamp casings


Recommended Posts

Headlamp casings scuff over time from dust and debris hitting them at high speed over time. Because they seem to be made of a heavy duty acrylic, is it possible to polish them with compound, or is it easier and fairly cheap to replace them? I'm getting enough light, but would get even brighter light if I polished/replaced.

 

I know that aquarium owners polish their acrylic aquariums, so thought that this might be possible with headlamp covers.

ive done it a few times. and i truly vouch for the 3m headlight restoration kit.

 

 

no im not trying to sound like a commercial. but be patient and it really works!

its about 22 dollars or so.. it was liek 18 i think when i bought it last year.

but my friend bought it again a few months ago and thats the new price.

 

 

theres two packages. i believe the older one does not included masking tape.. so its a tad cheaper.

 

good luck

Thanks, that is one long thread apparently with a lot of approaches. I'll have to read in depth later, but for now, in addition to sandpapers of several grits used with warm water and soap,

1) which rubbing compound would you recommend?

2) which clear coat or plastic shield or wax would you recommend?

 

Also, about how much does a new set of headlamp covers cost, OEM and non-OEM? Curious if worth the time.

Sorry, can't answer your questions about rubbing compound and clear coat--I've never gone that far with the process. I use a plastic cleaner but the housings go dull again after a few months.

 

Check some of the Subaru on-line parts places for new prices. But be prepared for a shock, I imagine they're very, very expensive! As far as aftermarket (non-OEM) I don't think I'd trust them to last.

According to Amazon reviews it isn't as thorough as the 3M kit, providing a quick easy polish but not getting out heavier haze or deeper scratches - would you agree? Any tips for using it?

 

It definitely seems easier and less work than the 3M, just not as thorough.

PlastX is great stuff for polishing the lens. I use it with a high speed buffer after wet sanding with 2000 grit to remove the fine scratches left by the sand paper. It also acts as a protective coating similar to wax that will prevent the lens from yellowing if used regularly.

 

As far as the kits go. I've never used one personally, but I've seen the 3M kit used several times by others and the results vary. It all depends on your attention to detail whether it comes out good or not. If you take your time it usually comes out better. I think either one could be just as successful as the other.

 

I did a writeup of my own with before and after pics. My method was to wet sand with various levels of sand paper then polish out with a buffer and finishing pad.

i bought the 3m kit with the drill attachment for 24$. i also bought a bottle of maguiers? polishing compound for about 8$. i used the compound in the 3m kit on the first day and did 2 cars, 4 lites. but since then i have done 2 other cars and still have polishing pads left for one more. so the kit is a pretty good deal. 5 cars for 32$. i didn't do any kind of clear coat.

 

they say if you use some car wax on the lites every so often they will last longer. so that's my plan.
