Anyone successfully painted the std grey plastic bumpers? Has the paint stuck successfully?

I've seen several painted by the dealers Barkers of Sth Millford in Yorks years ago, and within months, the paint was peeling off. Ask Tom about painting bumpers though to be honest.

yes so long as you use the correct primer you'll be fine, some of the original equipment bumpers were available painted or some models like the bohemia and a few others so you can buy them from skoda pre-primed ready to paint
