What became of the Line-X idea? We've had subs, wedges, drumfills, and sidefills finished with it for several years now and I'd never go back. They still look like new and some Armour-All makes 'em look even better. Occasionally, a little tear will develop, but Super-Glue takes care of that. Better than sanding and refinishing.
Would I re-finish our KF-760s with Line-X? Well, no. At least not until I talk to the factory folks about it first. And even then, I think we'll re-finish them with the EAW paint the next time and use LeCovers for the carts.
Still, it's just Line-X for us on everything else.
