Once I have finished a colour should I seal it with a clear or leave it until I do the whole playfield?If you let the paint dry, you can mask over the painted areas. Use Tamiya yellow hobby tape. I bought three reels of the three sizes from China and they were excellent quality. Clear should be applied before you start (for very bad playfields), or when you are done. sometimes you may need to lock in the touchups with a clear and then NOT continue with the next 203 coats in case you need to fix any of the touch ups.

If I leave it to seal later, how long should I leave it before being able to safely tape over it to do the next colour?With Arylics - 1-2 hours in summer. You can use a hair dryer to speed it up.

What is the best tape to use? At the moment I’ve been using 3M Scotch Blue tape.Tamiya model tape. I think Gav would have mentioned it earlier. Don't use the 3M stuff liberally as it is more expensive !

What’s a good clear coat to use?For EM / touch ups - I use Cabots and mix 80% gloss / 20% low sheen to flatten it and then use the airbrush without the needle. This is only for touch ups. Full CC, I use a professional to do that for me !

Is an Airbrush suitable to apply clearcoat or do I need a bigger spray gun? You can use an airbrush, but it will take forever and the product will start to dry and you will have problems identifying even coverage. Buy a HVLP Gun and use it ONLY for CC. I have different guns for different applications.
