Yeah I've read that, thanks... it always seems like a lot of trouble! But the finish is lovely, I'm just not sure I can be bothered with all the flatting down!
I'm thinking of doing mine with a brush... not sure yet though.
The best thing about the Matt is you don't necessarily need to flat back, I'm only planning to lightly sand down where I managed to get drips, before applying the last coat! The gloss White should be done but as on roof not likely that i'll do that!
My main issue now is how do I clean Matt paint!?!?!
