If you use polycarbonate, DO NOT use Loctite on any screws that you use to secure it. It attacks the polycarbonate.
It wicks into any cracks and can cause splits. Other solvents can do this as well.
Polycarbonate is available at B&Q but only as large sheets of thin 2mm material.
Available in allsorts of sizes online.
