Hi Paul, I use 3 types of CA, 1st a thin from screwfix 3 coats, 2nd medium from toolstation 3 coats an lastly thick from toolstation 1 coat. All used with activator between coats, buy from amazon 12 tins at a time at a great price. I use blo when I have inserted pine cones into resin, after sanding it brings out a deeper colour. Hope this helps. Tony
