Stopping rain beading on rear glass?

Silvia · Postby **Silvia** » Sat Feb 16, 2013 9:39 am

I find the rain beads on my softop rear window and makes seeing out hard in rain. :shock:

Is there a chemical that makes the water slide off rather than bead up like Rainex does?
Come to think of it, it would be good for side windows too....

Rainex doesn't work? Got shown a generic waterproofing chemical the other day by someone at work. Will ask if you want

Thanks , the front window is fine but it's the rain beads that sit on the rear window and don't blow off that's the problem.....
Might try dishwashing stuff - i hear spit works too

Rainex always worked for me. The rain beads up then rolls off. Does need a bit of speed though. Not sure how much needed for the rear, but 100kmph would rule out the need for front wipers.

Rainex works well on my old car with crappy wipers.

I've never tried it on the hardtop (it doesn't rain very often here), I don't see any harm in a good coating of rainex on the outside and anti fog on the inside.

SIGH!

why am I so misunderstood :?:

Windscreen is fine. :lol:

Rainex is wonderful :lol:

My rear window is obscured by waterdrops at any speed in the rain.
I'm looking for something to make those drops go away..

Hi Silvia,
Try giving it a good going over with quality polish, if you do not like the result a quick wipe with Prepsol will fix it. Keep both products off the vinyl. There are several products aimed at motorcyclists for use on visors, personally, I use dishwashing liquid (it contains polymers that encourage streak free run off) on my visors, a quick turn of the head and the beads break away.
Best.
Greg.
Auto Glym had a product on their list some time ago but I felt that it was the same as the wheel treatment brake dust stuff that they marketed.

People will whine about this comment but... Idc

Working on Sydney Harbour we would use AJAX spray and wipe.
It gets rubbed on via a cloth and sprayed off with a hose.

No beading, water drips directly off the windows. Doesn't affect tint either. Has worked for years on commercial vessels.

You're not being misunderstood - people are suggesting you try Rainex on the back window. You don't get as much airflow to help blow the water off, but Rainex should help the water bead and run off via gravity. If Rainex doesn't work on the rear window then I'm not sure any other product will have more luck.

You're not that far north of me - since 11.30pm Friday night 170mm here, 28mm just came down in maybe 15-20 minutes and still pouring so forget the rain drops!! I was down to 30kph Bribie Road with visibilty maybe 50m at most!! So much for my 'dry' coffee run this morning!!

Try cutting a potato in half and rubbing that across the glass, works fine on windscreens BUT beetroot isn't a good idea!!

I'm SERIOUS!! try the potato!!

Yes of course I've used Rainex on the back window too - worse visibility, as more raindrops sit on the glass without enough wind to dislodge them apparently.
:arrow:

Hi Roger Did the "white GT86 January" in your sig. actually happen?
Rain still pissin' down here.
I tried the potato once - someone told me that's what the Spitfire pilots used - it was a bit yucky and when I washed it off things returned to previous .
No, I'm thinking the Morning Fresh could be the go - either as a run off effect being a surfactant, or making the glass very clean so nothing on the surface repels water or causes beading.
Who would have thought the answer was so elusive.. :roll:

Yes, picked it up Thursday from Gatton, left the NB out there and went back yesterday to pick it up, so a nice 593km on the 86 now - link below will show some pics that page - still belting down here, lucky my place has great drainage but the cat is watching the 'flow' to the rear sump drain with envy!

Page 94 there are a few I took :wink:

Ross 'Trackphotos' took a few at Lakeside yesterday afternoon, talk about a pro photographer emailing you a bonus set of prints!!

Congratulations Roger :!:

I can well remember sitting in a new red one in May last year in a Toyota showroom in Fukuoka Japan.
Have to watch Bathurst now on SBS and forget the rain!
