How to strengthen a fiberglass flag pole for ATV/UTV use?

[INresponse]

I made some way cool flags with the customers logo on both sides, which means the material was double think so the images didn't show through on the other side. But the standard 1/4" flag pole is too thin to adequately support the weight and the flag pole bends too much when riding.

I have looked and the only 5/16" poles I have found so far are on ebay and at $15 each. Any thoughts on what I could coat the bottom half of the fiberglass pole with to strengthen it to reduce the flex? A coating of fiberglass resin would work but it sets up so fast I could only do a few poles with each mix, same with epoxy. I can't use a metal sleeve as it has to be able to bend during a roll over. I know I am grasping at straws but I am hoping someone has an idea.
Thanks in advance.

Bend during a rollover? I won't ask.
How about copper? It'll bend.

insert pole inside a PVC pipe?

Acetone should remove any markings on the PVC.

How about a long, tightly wound spring? They use them to support copper tubing etc.
