I actually hate myself at the moment, I'm sooooooo stupid. I've just fitted a brand new windscreen to me TR6, having (I thought) got all the messy tasks which might injure it out of the way. At the last minute I decided to fit an additional (original style) switch to the dash for front and rear foglights. This involved widening a switch slot to accept repro switches. Masked up the cockpit trim, whipped out the Dremel – job done. Or so I thought. A narrow jet of sparks had whizzed up past my masking and bksed a three inch by two inch patch of windscreen in the 2 o'clock of my line of vision. FFS. furiousrage etc.

It's not that bad, but bad enough to irritate and of course will be a nightmare at nigh and in sunshine. However, looking around it seems I might be able to polish the damage out.

So, does anyone here know:

a. Is it possible to polish out this kind of damage?

b. If so, is this the sort of thing I can do myself?

c. And, if so, what and where can I buy the gear to do it?

d. Or is it better to cut my losses and stump up for another new windscreen? (which I really don't want to do – project way over budget already)

Be an idea to send Glassman a pm.

Having done the same silly trick I used a razor blade very carefully to dislodge the bits of metal. I was lucky in that it didn't affect the view through the glass.

There are also boaty things out there which are used to remove rust staining. I can say they also work to remove grinder debris which you didn't notice until the rust appears. The one I use is Starbrite Rust Stain Remover. Google will bring up videos about it.

I haven't tried it on glass but it does the job on gelcoat & boat paint without damaging the surface - beyond taking the shine off which was easily rectified with a quick wipeover with a bit of polishing compound.

Try some Fallout Remover first and see how that goes. If It's not too deeply etched into the glass you'll be ok with just that.

If it then leaves etching behind you can wet sand glass back with ever decreasing grades then machine polish but it's a long winded process
