Reedster,
That is true about grinding down the Rino lining or Line-x.
Builder,
The only problem is that my soul won't be able to rest in peace if I knew when i passed it down to my kids and then hopefully to my grandkids that would have to go back and redo it. I guess, and this might hurt the pocketbook on my project, that I'm the type of person that when I do something I'm not going to be one to cut corners or half way do something. If I do it, I'm going to do it right the first time.
