So, on my first rod, I had a little blunder involving drying flex coat and a synthetic fleece sweater...on the area where the logo of the rod maker's name, so there is a lot of flex coat and no wraps in that area. I tried to burn off the little fibers that got stuck, and ended up scorching the flex coat somewhat before the flex coat had a chance to set, but couldn't think of a way to remove it without hurting the blank now that it has dried.

Any advice would be useful.

Thanks,
Ken

Ken,

Been there, done that. :>(

If you can turn the blank on a lathe, you can sand the finish down until it all traces of the fleece are gone, without having to completely remove the finish. The more set (cured) the finish is, the easier it is to sand it.
Light pressure and reasonable speed. The thing you don't want to do is to heat up the finish as you are sanding it.

You can sand by hand, but I don't know how good you are to go that route.

If it is soft, or it has softened up, you can peel/remove much of the finish using a fingernail, old credit card (or you wife's creadit card) , a popsycle stick. Anything except a razor blade.

I use an emory board in cases like this given you have a liberal amount of finish coat to work with. (thickness)
