I've just taken a mould from one of my cycle wings and have been pleased with how it came out so far. I feel giving it a quick polish would help improve the quality of the finished product even though visually the mould looks good now.

Do yourself a favour and give the Pai Crystal range from Easy Composites a go! The NW1 cutting compound is far and above the best compound I have ever used, and I've used a lot! That on its own will give you a very good gloss, but I also always use the Easy Gloss Black which is the second stage in the system. It's magic stuff.
