Welcome Richard and thanks for the tip. I will be on the look out
for that paint so I have it around for the "next time".
By the way, I am the group stooge here. I am learning a ton from
all of these guys and it's been great. While I still can't do too
much on my own yet, I have learned SO MUCH, that it is scary.
Frankly, it is one of the groups where we can all speak pretty
frankly with each other, debate some things, and at the end of the
day, everyone is still cool and it seems as though everyone gains
(especially me).
Hope to gain some of your knowledge too!
Chris
