MY REPAIR
G'day ClaytonRV6,
I posted several months back - search on 'Cracked Canopy'. There are other threads.

I repaired the crack using Weldon #3, and the stop drill holes with Weldon #16, as per the first post. The #3 did not wick very far in the crack, so I applied it along the length of the crack using a fine point syringe while trying to hold the plexi even along the crack while the #3 cured. Then I used a larger tip syringe to fill the stop drill hole with #16. The repair looked adequate.
Following advice on an Australian forum (SAAA - Sports Aircraft Assoc of Australia), I re-did the repair using Acrifix 192 (Acrifix 1R 0192, go
www.evonik.com/acrifix-1r0192). The repair was a definite improvement helped by: the lessons learnt using WeldOn; and easier application using the Acrifix tube (think toothpaste) vs the medical syringes used for the WeldOn (pint tins).
I dressed the repair on the outside of the canopy using a MicroMesh repair kit from Aircraft Spruce. The crack is too close to the left rear canopy bow, so I will dress the inside of the repair next time I remove the canopy - probably I would cause more damage if I dressed the crack while the canopy was on the aircraft.
The MicroMesh systems worked well.
Although the crack is obvious to me on the ground, I do not notice it in flight, and can not see it with a passenger in the left seat.

A few flights later all going well up to VNE and 0 to +4G.
Good luck with the repair.
Regards,
