I've been building my first plug for the air conditioning housing on my Marcos Mantula. While I'm quite happy with the way it has turned out in general I am finding the application of the pattern coat primer to be more difficult than shown in the Easy Composites video. I've tried using a brush and a roller, but can't seem to get to the stage where it only needs minor sanding. There always seems to be new imperfections with each coat.

Yeh it's a pity that Duratec products are so hard to get hold of. I've actually lost my supplier here too, they no longer sell it, so I'm on the search for an alternative. Have found a high build PU that may be similar, so will see how it goes.
