I’ve just got around to fitting my Fairbourne screen (after it’s sat on my garage shelf for over a year

!) It's not too tricky to fit as long as you aren’t in a rush and can afford to take it steady.
As others have mentioned, there is a risk of damaging the paint around the screen slots when trial-fitting the new screens. I covered the area around the slots with masking tape as a precaution.

Also, if I was doing the job again I would grind off the sharp edges/corners along the lower edges of the new screens so as to further protect against paint damage.
When the new screens are trial-fitted you need to mark where to drill the 8 mounting holes but space around that area is very limited so it’s a bit tricky! I found that a sharp 1.5mm drill bit was an ideal scribe for this job.


Final tip: The tiny wood screws that hold the drip guard in place are also very fiddly so I replaced them with more 'normal' (Pozi 2) headed self tapping screws.
The weather hasn't played ball so I haven't driven with the new screen yet. However when sitting in the car I was pleased to find that I can easily look around the screen if ever I need to.
I haven't applied fresh silicone around the slots as mine is strictly a dry weather car and if I am caught out in the rain then hopefully the drip guard will do it's job. This decision will be reviewed depending on how wet my knees get!
