Acrylic Problems
Posted by Yimkin on Saturday, February 7, 2009 7:02 PM
Hi all,

A returner to modelling after 25 years - in other words, the last models I made looked like the one Calvin made in Calvin and Hobbes - I'm trying to avoid that now!

My first model was an Airfix Hurricane, which I was very pleased with - a basic kit coming with it's own acrylics.

However the second set I bought was the Airfix Falklands War set (a step up from 1 to 2 in skill - ambition!). I started with what looked like the 'easiest' model - a Super Etendard - however a lot of it is white (humbrol acrylic no 22). I am having serious problems with this - dark colours on this and the Hurricane go on well, but the white paint is like water, and all I am getting is runs and patches of the original grey base colour of the plastic kit.

What do I do? I toyed with buying white auto primer and using that instead, but not sure if it will melt the plastic. Could I paint on a grey primer acrylic and cover it with no. 22? Any clues? I tried sanding, but all it did was remove the previous coat. Any guides to using acrylic?

Sorry, I realise this is a blindingly obvious question, but if the answer exists here (have searched a lot before joining) I've missed it!

I'd also really appreciate a link to a guide to how to fill gaps, what sanders to use, and also how to stick on canopies without getting my fingerprints etched into them - PVA glue?!

Many thanks

Chris

Most folks use Elmer's (white glue) for canopies. If you use pastic cement/liquid cement, you are asking for trouble.

For gap filling, you can use super glue (Zap-a-Gap thick ) is the best brand I have found for this.

Also there are many model putties out there such as Squadron white and squadron green putty. I like Tamiya putty personally. 

A recent issue of FSM recentlly had an article on filling and sanding gaps. You may want to order the back issue and read up.

As far as white paints go:

White paint is very difficult to hand brush because it usually takes several coats to build up an opaque layer. Most manufacturers white paints are not very good. The ones that are good (Tamiya comes to mind) do not hand brush well because they dry so fast. If you do not have an airbrush (best way to paint anything white because you get even coats and the paint drys faster because the coats are much thinner than when you hand brush), then I think your best option would be to pick up a can of Testors Flat White enamel spray paint. Even then, you will probably need a 2nd coat before everythign is opaque. If the base coat or plastic is a dark color. You could spray on a coat of sliver first; however, this will make you top coat difficult to mask over because any paint put on over silver will generally pull off if you put tape over it.

To summarise:

Option 1 Spray Can

Option 2 Airbrush

On the Bench: Too Much

Many thanks cbaltrin - I think I'll give the spray can a go first, not enough cash or talent to splash out on an airbrush yet!
