Thanks guys, What I stuck in the cp is a suggetsion from Rjkplasticmdo (Rick). He uses fun foam but I use make-up sponges, courtesy of my wife! I cut it to a size just a bit bigger than the cp and then I stuff it in, it doesn't break the little pieces inside the cp and it totally blocks any paint from getting in. I tried the wet papertowl or tissues but I just got little fibres stuck everywhere inside the cp.
I got the dark green on last night. I am impressed with myself, I had my doubts for a few moments there but it looks great! I'll take pics tonight and post them tomorrow. I now have to paint the mottling and the red for the underside.
