grit needed to apply epox

Posted by Patrick Forrester on Jan 27, 2007

I have removed the glass from the bottom of my wr18. I have a smoot thrasition from raw wood to the glass I did not remove.

I am going to overlap the glass. I need to sand some of the existing glass ( 2 years cured ) so the glass overlap will adhire.

What is the minumum grit I can use for this purpose. I prefer to not use a course grit so the final sand is easier and less intrusive.
