I'm looking to varnish a painted pvc pipe. I'm not sure if I should even use varnish, I just requirement to make it cut into and mark resistant.

Thanks surrounded by advance!
try radiator varnish


paint and varnish do not adhere capably to pvc
as your pipes are already coated try a clear spray on lacquer it may give some rank of abrasive protection.
best to maintain some touch up paint handy
Answers:    use clear lacquer. its matching stuff they use on guitars, so its pretty tough, scratch and splotch resistant. its best to use a spray lacquer to prevent brush marks. do it tough layers at a time, and you wont bring back drip marks any. you may want to practice with a spray can first if you havent used one back.
