Maskol, a question

[NARSES2]

The Whitley's many tiny windows will mean using Maskol which I don't really use that often. Anyway the bottle says don't leave in on the surface for more than 3 days.

What happens if it stays on longer ?

It dries out completely, and if it has been on long enough will need to be sanded off. I know from experience.

One trick I have found to delay this problem is, let it dry overnight then paint over it completely, this keeps it from getting too dry.
For this enamel paint is better than acrylic.

It hardens & can be a right PITA to remove. I've found that if a coat of paint goes over it very shortly after application you can get up to a week of easy removal, in cool weather.

Two minds with but a single (excellent...) thought. 

And only one minute apart from each other two.

I leave the clear parts off and make the "glass" with PVA after i've painted everything.

I do too if the windows are small, but for big ones it's not so good.

The upper canopy windows on my Monterey are around 3/4" square. [That's 19mm for those who are Imperially challenged....]

Yes, but on Chris's Whitley they will all be tiny.

Oh sure, as on many WWII subjects.

Yup, but unfortunately I was so intent on following the instructions I used the clear parts    Should of used PVA.

Anyway thanks gents, most helpful  The plan is. Day 1 put Maskol on and prime with white. Latter in the day Humbrol Appliance White. Day 2 upper surface colours. Day 3 varnish coat. So I should be o.k. as long as I keep to that.
