Noticed today on the pug, I have a hefty stone chip on the passenger side, with two very short impact lines (verging on cracks) eminating from it at opposite sides. This picture is shocking quality and I stuck my finger in the way to try and give a sense of scale.... I would estimate the chip is approx 7 to 8mm in total, was a hefty stone! and the two cracks are both around 5 to 8mm?

MOT regs appears to just say "chips OK, cracks not OK"....

They are going to spread slowly to the edges of the screen, then they will be well and truely cracks.

Possibly, but at the moment, I am only a wee bit concerned about MOT in two weeks. Chances are a replacement screen will cost me half what I paid for the car.... Wondering if I should dab in some gunk to attempt to stop it spreading in the short term.

Dont you have windscreen cover, should only cost you £60 for a replacement via your insurance.

You can buy a window repair kit in halfords that I've used in the past to good effect. Get one or the chip will turn into a crack ( ooh vicar) .

Ive had 5 windscreens on my ibiza all from stone chips turning into cracks ( ooh vicar) .

Dont you have windscreen cover, should only cost you £60 for a replacement via your insurance.

Not sure as the car only cost me £150 I have only done third party cover. I want this to be a cheap runabout, not something that actually costs me money

Worth a stab...

the definition for a mot this, imagine a vertical line drawn up from the centre of the steering wheel, basically an area 290 wide inside the swept area of the wipers, the max limit for a chip in this zone is 10mm... anywhere else its nothing longer than 40mm chip/crack

anywhere else its nothing longer than 40mm chip/crack

Thanks. This is definitely on the passenger side, so 40mm rule should apply. Its definitely smaller than that, I wonder why the MOT site I went on first never mentioned 40mm as a measurement. Oh well. Seems like a quite critical thing.

Might be cheaper to bump your ins up to fully comp then claim the windscreen in a few weeks.

Sometimes fully comp can be cheaper than tpft too.

Autoglass charged £45 to repair a chip on my missus' car last year.

Has to be a chip/small crack less than the size of a £2 coin.
