BigShrimp,
Whats the difference between dougfir and dougfir marine ply?
Is one softer than the other?

Strick,
what type of tool did you use with that disk?...how many amps was it? Do you recomend a particular manufacturer?

Thanks for the responces.

Still looking for any info on the size of the tank I have and why nothing my boat was cored with plywood or anything.
