Thank you, gentlemen!
Must admit I'm rather pleased with how it came out.
How does one go about doing that? I've often wondered.
First: Mask the outline of the overall area that you want to chequerboard & paint it in the lighter colour.
Second: Overlay a cross-hatch of the appropriate width masking tape (in this case 4mm), ensuring you have the correct gap between by using a piece of the same tape as a gauge, & paint the darker colour (an undercoat may be required if the colours may interact (eg: you don't want to paint red over yellow without a white undercoat, unless orange is OK)), & remove once the paint is dry.
Third: Overlay another cross-hatch of tape, this is somewhat easier (especially if you have somewhat translucent tape, like Tamiya tape, etc.) but you will want to use a tape gauge again to make sure in some spots, & paint the second (darker) colour again.
The other option is to mask the edges of the area & cross-hatch mask 4 times (twice for each colour) but I figure that way lies not just madness but also an unacceptably high (for me) risk of stuffing something up.
Hope that helps, Brad.
