3M headlight lens resto kit for windscreen

Discussion in 'Reviews' started by blueline15, Jun 9, 2012.

  1. Well, I got around to attempting to refinish my windscreen on my SV650. Ultimately, I want to replace it with a darker one, but for now, I really wanted to kit rid of the grunge and orange that had developed. My overall impression is that this kit met my expectations. I didn't exceed them, but it met them.

    This started with this thread:

    I bought the 3M kit on, for $12, and it came with a $5 mail in rebate. So only $7 total expense. Not bad. Saw it in a store for $18.95.

    This is what the kit looked like.


    And this is everything inside of the kit.


    Before, you can see the "yellow" that runs through the screen.


    Windscreen is cleaned, but this crap always stays behind


    This is after the first step. Sanded with the 500 grit discs, both sides.


    This is after the second step. Sanded with the 800 grit dics, both sids. You can't really see a difference, but you can feel it. It got noticeably more smoother.


    This is after the third sanding, and it is a wet sand with a 3000 grit pad. It's slightly more clear.


    This is after polishing it with the rubbing compound, both sides.


    You can see the yellow is gone.


    But it's still pretty hazy.


    It definitely looks better, even though it still has a frosted look. I did buy Meguiars PlastX, and I have been buffing the hell out of it with that today. Every time I did it, it did get slightly clearer. But I'm riding tomorrow, so I put the screen back on for that. I'll probably pull it back off when I get back home and continue to buff and polish the screen with the PlastX, and which point I'll add another pic.

    That's my results though. Truthfully, I feel like it looks better in person now then what the picture shows. It's not that noticeably grungy anymore, even though its still frosted. One final pic of the windscreen after polishing, looking back on the bike.

    I have never tried that on a windscreen, but have had excellent results on plastic headlight covers. I would imagine the windscreen is softer material, which could be not as easy to polish. You did a fine job, might give a product called "Plexus" a try. It's a plastic cleaner and protectant, a polish designed for aviation windscreens. It fills the microscopic pits and polishes to a rain shedding shine...AJ

    You can also try (for Darkening this shield) A transparent candy color.(spray on the inside of the shield) Like you find at a hobby store that sells plastic models. Or, spray paint the interior with Silver or Gold.
  4. This is good to know, the windshield on my Goldwing is getting pretty hazy. Been rubbing it out with Meguiars Scratch-X, and then rubbing it out with Plexiglass polish. I think I am just going to start looking for a new windscreen, wanted to cut and black out the old one for a different look.
  5. You're right. I think the windscreen is a softer plastic then the headlight plastics. I felt right away that the 500 grit was too strong, as it removed a lot of material, very fast. I spent a lot of time with the 800 grit, and then the wet sand 3000 grit and polishing compound. But it was worth the $7, and I wasn't too worried if it really screwed the screen up. I'll look into the Plexus, might pick some up. I want to continue to buff this thing...but tomorrow I ride. :mrgreen:

    I thought about just painting/darkening/tinting this screen before buying the polishing kit, but figured I'd be the guinea pig with this project first. I'll probably still do something like you're suggesting, and if that doesn't look very good or work very well, I'll just replace it with something aftermarket.

    Glad this had good timing. Figured somebody is or is going to be in the same boat as me, and can make their own decision based on my results.

    Another thought, wonder if a person could go to Wally World and pick up a roll of "Do it yourself" window tint. Then precut to fit with over hang on all sides. Then roll both sides to the middle after spraying on the slippery stuff. Work it out with a squeegee from the middle and when the air bubbles are out, trim with razor knife. PS applied to the inside almost forgot. PS II; I believe aftermarket windscreens are in the $100. range???
  7. I'll probably try that out later. I'm familiar with using the soapy water method to lay out large decals on windows, so I'm sure I can do that. Either that or paint it, not sure which yet, except I think I'd like to look of a very dark smoke over a solid color. And the dark smoke would hide the haze that's still there.

    I'll eventually probably get an aftermarket windscreen though. You're right, they're around the $100 mark, but I'm planning on coming back to the PNW for good in september; but it will cost over 2 months of pay to drive back in 3 days!! :scared That gives you an idea how piss poor an AmeriCorps stipend is. For the time being I'm keeping every $100 I get! :)

    Thanks, it was a good Saturday project. My shoulder is tired!
  8. Looks great man, I will have to try that if my windscreen starts looking like crap!
  9. If you went from 800 to 3000 grit that is a big jump. Maybe find some 1000, and then 2000, and then after that try 3000. Not exactly sure where you'd find that range other than an auto paint supply store and I haven't looked for any in a while to suggest where else you might find it....

    By hand it wouldn't take too long to use those grits and it might help clear it up more too.
  10. :thumbup: Just wanted to report my results as-is.

    I agree that that's part of the reason it's still hazy. It took a while to get to the clarity that I did, the sanding marks that are there are not deep, and I believe they are from the 800 grit pad, that the 3000 grit couldn't remove. I think that's part the difference of using this on a windscreen and not a headlight lens; the plastic seems softer.

    I'll look around locally, but I live in a very small town, and not sure if they would be available locally. I imagine the handful of somewhat local auto body shops probably order in large quantities.
  11. Any sort of hardware store should have sandpaper, maybe even in the grit that you would want... I know I got 1000 grit at a Fred Meyers... and their sandpaper selection blows.... It might be worth it to check :mrgreen:
  12. Never tried it but I've been told to coat the edges with clear fingernail polish if you use window tint on the inside. keep it from peeling up.

    P.S. Thanks for the write up.
  13. I'll scope it out. The Ace hardware here is inside of a grocery store. :roll: But there are some other mom and pop shops I'll scope out. I'll update if I go back to a 1000 then 2000, then the 3000 grit with a polish again.

    I think this is a good representation of the results the kit gets you for the average guy like me, and a follow up going back to smaller steps in grit to see if the results improve would be worthwhile incase somebody goes down this road later. Save them the time to know if it's worthwhile to pick up some extra sanding pads.

    Thanks for the tip!
    You're welcome. This is my one yearly contribution to the forum. Glad I got it out of the way already. :mrgreen:
