I've used styrene half rounds for trim that had probably the same needed radius on corners. I would use liquid plastic glue and do in short sections about a half inch or so. I just lay the strip down and touch with small glue brush. For the radius I'd put son glue on and it bends easily around the radius and sticks. It may be tough controlling the edge you need with half the half round sticking out from the edge. Might need a bit oversize round but it is industrial.
here's a few pics of how much the rounds bend with a little glue softening ..
These taillight shrouds were made with half rounds the same way, bending around the taillight lenses
