Thanks everyone - I'm not going to lie - there are some defects in it. I'm not sure but I think the problems started with the first coat of RPC. I think it went on too thick and created too much unevenness. So it in an effort to remove the lumps and bumps it went too thin in places. Especially on the under side. But I can live with it - especially as the top and back look nice.

I think the main point for me is progression from last one - as long as I keep getting better I'll be trending towards a perfect finish.
