After several goes i decided to try a two pass which was better than the first lot then I did one pas/stroke (not sure what the correct term is) ..then flash cure then another pass.
This was much better than the others but while i'm aware that there is a lot of practice to be done it's the fine hairs that you can just see through the white.
Whilst in the practice stages we are using 43T until our other screens arrive.
By the way I ought to mention I managed to get paint on the ceiling, floor and dads trousers, daren't look closely at anything else
