I think Kurt Z. figired it out.... It's silkspan and its painted with Hobby-Poxy. That's why lacquer thinner removes a little of the paint but does nothing to soften it..... Although it does come off the bamboo rather nicely....
So I guess I'm going to have to use the two 20 year old cuties as Brian Chan suggested.... :-))) Actually I have a friend who has some 6' long 8" wide sanding belts. I'm going to glue them to my work table and make one big ass sanding block...
