Yeah, I've used it a fair bit. Brilliant! Just follow the instructions.
Make sure you let it dry/cure completely before painting over it though. It dries and goes black pretty quickly, but you need to wait until its gone purple before painting. Takes between 1hr and 2days depending on the wheather.
Make sure you wear gloves.... will stain your hands and nails a lovely dark blue colour for about 2 weeks.
thanx dopplershift, all info is usefull, I note you're from perth w.a. just been there a few months ago to visit relatives, gr8 city,love the glass clock tower,(english clocks of course)
Yeah, Perth is pretty good. Funny about the bell-tower though (was very controversial!).
Hey, I forgot to mention: I think the Fertan instructions say "do not overcoat with acidic products" or something like that??? Could never work out what that really meant... no etch primer? Never tried it though, so I'm not sure what would happen.
