I use Uni-mould and I love it but my neighbour complains because of the smell.

You won't have an epoxy solution like the EC pattern coating system. Polyester polishes up much nicer and easier than epoxy, so it's a good system for pattern coating. That said, when I was first starting off, I used high gloss laminating epoxy thickened with a bit of calcium carbonate (not too much, it's difficult to sand!). This worked quite well, though it took a few hours of sanding.
