Sanding sealer

Ahhhh, the joys of tradition modelling. Who amongst you whipper snappers with your X-Boxacto knives and your Resistance Soldering Units, has ever used sanding sealer ?

Not many I suspect. Well sit at Grandpa Phil’s knee and let me explain.

Imagine you have some wood. Yes real wood from trees, not some plastic imitation. You would like to paint this wood. Now you might think that all you do is open the tin, stir the liquid and slap it on in the approved manner. What you will end up with is a hairy mess.

Wood has grain and is made up of fibres. So, before paint you need to seal the surface or the liquid colour will make the grain and fibres rise – giving the impression of a model that’s been too close to the cat.

The trick, if it can be described as such, is to paint the wood with sanding sealer. You’ll have to search a bit for this, as most model shops don’t carry it. Model aircraft shops are the best bet, or Squires. Sanding sealer is made from the blood of frogs harvested at midnight or something (I might have made that bit up) but the trick it performs is magic. Balsa wood is converted to a smooth substance that feels like soft, warm plastic. Paint now forms a beautiful smooth surface. The brush you used is probably dead though unless you wash it out in cellulose thinners. A small price to pay I feel.

Of course you could just use plastic in the first place. It would save a lot of mucking around.
