Windscreen Coating, smearing etc.

[bazzle]

I'm finding it hard to get a clear wipe on my screen. IS350 F Sport 2011.

I've changed blade assemblies, scrubbed screen with diff chemicals etc, added bars bugs etc etc.

It looks like there is a coating over the whole screen that doesn't want to be removed.

I read that some Lexus models used to have an coating from the factory that wasn't removable but became an issue as it wears?

I also get poor vision if the sun is directly thru the screen, early in the day. Makes it look like its sand blasted but its not!

Any clues?

Isopropyl alcohol all the way.  Wiped down with a clean microfibre cloth.

Thanks.

Tried that and Prepsol.

Continuous use of bars Bugs has helped a little but it looks like there is a fine mist of overspray all over the screen but there isnt :(

I think it may be in the flexible layer between the laminated sheets.

Ahhh fixed :)

Mixed up a paste from the grey ash from my wood fire, rubbed all over windscreen, washed off. 99% improvement.

There must of been a fine overspray from something all over the windscreen, may of been the Lexus coating??

Anyway can now see when sun on screen and raining

Good one were did you find that solution cheers.

did you buy the car new or used?

 

[bazzle]

I got it used.

I use the ash solution to clean my wood heater glass window. :)

[ilv1004s]

thats great to hear!

was going to suggest probably had some chemicals on the windscreen if the car has been to a panel shop

happened to mine when i got the guards replaced

You could  be right as well.

who knows what was done to it for prepping at the Lexus dealer 

 

edit: still some on screen. Will give it another go later.

Try Autoglym glass polish.Fixed my wipers skipping/grabbing on the screen.Think it's just an accumulation of road grime diesel etc.particularly if it hasn't rained for a while.

Thanks Tony.

I tried bars Bugs neat earlier which has similar properties. 

I think ilv1004s is on the ball with overspray.

I will try  carefully with thinners another day. 

Panel shop told me to use 000 steel wool but I can find any that fine and they had none ;(

[ilv1004s]

there is a product that acts as a polish for glass try that a go

also removes small scratches too

[bazzle]

Must be thinking alike :)

Got some tonight. Its like a fine pinky powder. Old name I think is Jewelers Rouge.

Came with an applicator block too. 

Dip damp block into powder and apply with block.

will try out on weekend.
