I bought an ex-ME (Dutch equivalent of SPG I think) truck wich, amongst other things, is fitted with polycarbon windows.

You can barely see through the front-side windows as the surfaces has tiny scratches in it and it has weathered due to general use and exposure to all sorts of weather.

I reckon if I can polish the toplayer they will become transparant again?

How to polish them, what can be used?



One of the extra's on this truck is that is has a shute in the floor that was used to drop teargasgrenades from
Another extra is the 40 kg bulletproof grill

It's powered by a 3.8 litre 4-pot diesel with a slushbox and it is what they call an industrial diesel wich means it'll run on just about anyhting and has a longer life expectancy that the current owner

 

...i reckon Simon SECS will be needing a ride like that soon

 

If the polycarb has been subject to lots of UV then no amount of polishing will help it - you might have to get new ones made. They only have a life span of about 2.5years.

I use Poorboys Spray and Gloss (its an anti-static spray for the buftys) on my polycarb windows and use a microfibre cloth to wipe it clean. Using a sponge or cloth will leave scratches. If you havent got access to an antistatic spray just wash them with warm soapy water, but you need to use a microfibre, anything else will scratch it.

 

Not the answer I was hoping for

See, they are set in huge steel frames as they are ment to be bulletproof so removal will probably take ages and be an akward job

I do so love my new 'van' though, at nearly 4 metric tonnes it's not quick but it'll easily drive through a house

 

Pics or STFU forgein bloke

hows it going mate?

 

Oi Kev!

I'm allright mate, you??

It's a Merc 508 with double air

i,m fine mate just had a change of scene away from cossies the last year

this truck a big 4x4 or 6x6 thing then?....you should come offroading with us lot

you must have too much money if you can afford to fuel that cherokee as well

 

Thats the one and only downside with polycarb. At decent thickness it is indeed bulletproof, BUT, even rubbing your finger across it will cause fine scratches that cannot be removed. Perspex/acrylic is not as strong from an impact point of view but any scratches can be rubbed down with fine grit paper and buffed to a perfect shine again.
I used to work with clear plastics as a fabricator and hated polycarb, everything you do with it is horrible, forming it and welding it is so difficult as it bubbles and thats it.
If it was one deepish scratch that was bothering you it could with time and skill be removed with direct hot air but loads of surface imperfections and general discolouring is irreversable. If theyre flat panels it shouldnt be too costly to replace mate. There MAY be a meguirs product for it as I know they do loads for the plastics industry, we used a certain grade on acrylic and it realy was like magic.

 

you want to get some farcela plastic scratch remover comes in a toothpaste style tube and im pretty sure Demon tweeks sell it..

Give them a call or do a google search but you can definalty purchase it.

Plastic 4 performance recommended it to me works a treat.

 

yup they do the same stuff for polishing rear plastic windows on convertibles, i used a mop and some g3 before and that btrought up good results too

 

If you mop it - you will remove the UV layer protection on it.

Swings and roundabouts.
