Scratches on the Lexan F8 back glass??

It's very susceptible to scratching and once it's scratched that's pretty well it. The pros out here appear to have learnt the hard way not to put ceramic coating on it as they have been to clear to me they will use it on the glass but not on anything lexan as there are big problems - hazing along with impacting the visibility. Just use a moist microfiber cloth or microfiber chamois to clean.

 

If there was something that could be put on Lexan to stop scratches it would have been available long time ago not because Ferrari decided to put a lexan lid on their car.

It will scratch for sure just as temps from the engine and sunlight will affect the Lexan.

IMO if the car is a long term buy a spare hatch while you can still get them and are relatively cheap

 

Might try PLEXUS as a cleaning/protectent as it has been used for Gen aviation plexaglass. Is it 100% --NO. Flood with lots of water and microfiber towels. Never clean when PG/Lexan is hot. Then apply Plexaglass as a cleaner/protectant. Micro Mesh TM makes Repair kits that have various high grade miicro sandpaper/lube up to around 8000 grit. Go to aviation products & become familiar about what 's what out there for Leaxan/Plexaglas etc. I sold my plane about 4 yrs ago & have not remaned current. Talk with high end aircraft repair etc on this issue. Good luck. Can't understand Ferrari doing this over the engine as dust,sand,& heat are major deterrents to long term duration.

 

Hello,

Micro Mesh was developed in 1966 and it is a cushioned abrasive capable of leaving a surface scratch pattern at one ten-thousandths of an inch (.0001).

It is great product, I have used it for many, many years in my professional art studio on various plastics, cured finishes, metals, stone and other surfaces. Their range tops out at 12000 grit, not 8000 to clarify.

The military uses it on clear aircraft transparent surfaces to remove scratches. Micro Mesh is a cloth based cushioned abrasive with a flexible binder that holds the abrasive.

I can post a photo of the Micro Mesh if this would assist/advance the discussion and you can PM me if you have any questions. I have 25+ years of experience using this product. No affiliation, just a satisfied user!

Cheers!

 

I'm going to acquire a piece of Lexan to experiment on and report back.

 

Will do. I just ordered four test pieces - 4" x 4" x 1/4".

 

Looks like around $6,000 usd

 

Test pieces arrived today. I'm looking for suggestions as to what I should use to scratch it - something that might closely replicate what we might encounter in the real world. A green Scotch Pad may be a good starting point or perhaps something a bit less abrasive. Please chime in with suggestions!

 

Try a key. I'd also be cool if you could see how hard it is to warp.

 

Or use 800 grit sandpaper to simulate a light abrasion.

 

Anyone who wears glasses well plastic lenses knows you never wipe them with paper towel

I would do that first

then I would get a microfibre cloth wet it add a bit of sand and wipe the lexan

 

So you're suggesting two forms of abrasion correct?

 

Not that I would ever do such a thing, but I wouldn’t be surprised if people touch the glass while wearing their wedding rings. I bet you can get some scratches on it that way too

Yep.

 

Wash the car as usual, then use Plexis to clean the Lexan panel. Works great so far, no scratches…

 

Rob , I’ve also used Plexis on my clear bra and it leaves a beautiful shiny finish.

 

I had clear window film put on the Lexan or "Gorilla Glass" windows of several of my Porsche cars over the years without issue. Essentially a PPF made specifically for that purpose and provided additional impact protection as well.

3M and Llumar both have products that I've used without issue.

 

The Llumar is great stuff. It's sold under the Suntek brand in some countries.

 

Well I can tell you how my grandson scratched the H out of my lexan golf cart windshied which for the most the part is what happens over time with exposure to car, planes etc. Yes you get a real scratches which will be like a key type or the ring scenario, but those will be rarer & I'll tell you are not going to be satisfied with your approach to scratches that you can feel easily with your fingernail. Basically in these situations you must remove lexan product which can cause it's own problems. Correction of deep scratches if possible I believe is best left to the expert . My grandson took a clean bath towel marginally wet and cleaned a moderately dirty warm new lexan cart windshield achieving fine swirls, linear long scratches,and visability problems esp sunlight. I had my aircraft lexan door windows refinished professional 1 time and it was satisfactory.

 

If you have kids, let them play with it for 30 minutes...

Just wash it with the coarse side of a kitchen sponge. That will give you a hazy look very similar to what you get after a few years in the outdoors.
