I galvanized some roll bars and hoops that turned out really nice and wasn't too expensive.
If it were my "new" Land Rover, I would ask for a couple of hundred back to cover your time.
Years ago I bought a really nice Series III Carawagon from Blanchard and they were fantastic to deal with.
Couldn't tell from your post if the paint was dry as I thought you were complaining about some scuff marks on a roll bar and streaks of black on the inside of the top.
That tacky roll bar sounds like someone used waxoil or at least had some in the paint mix.
That shit is sticky and took about 10 years to harden on a 109 we owned.
A bunch of tacky golp inside your vehicle is a pain in the ass, it ruins your clothes and then next thing you know the goo is on doorknobs, the TV remote, your car keys, and so on.
Big pain in the ass.
Uncle "Richard" Douglas has a Land Rover with big wheels that never gets stuck... until he breaks something so it won't go. Uncle Douglas always breaks something. - Anna Crowther at the Conclave 2012 (AKA Carburetor Neck)
