If you already have a router on hand, just take nice pvc pipe and make the flares directly into the woodpanel. Just make a square to double up the panel insert the pipe and let the router do the trick. The final optic can't be beaten - no irritating plastics on the visible panel. In the end very easy to do and just some additional sawdust 🙂
