Nice faq... I like seeing the rationale behind your decisions too.
HEy, I even get a mention in the faq re: getting black handled twisty grips...
FYI: they were two different suggesions. One suggestion was to "paint" the pvc with truck liner paint... The other suggestion was to try RIT fabric dye or plastic dye..
no biggee...
good luck with the faq/site/project!
