Nitro Block Vs Window masking

[eyeayen]

So I've finally managed to finish a shell, I'll post some pictures up at the weekend although I'm hugely disappointed how it's turned out

Anyway, that wasn't the point, while I was doing it it became apparent I'd put the mask on too thick, not a problem I can sort it next time. However once I'd finished it I used Aerosol Nitro block, however the windows were then really difficult to unmask.

From previous experience with using Liquid Mask and solvent based paint it doesn't like it if you put it on too thin but as already mentioned for this water based shell paint I think I'd put it on too thick ?

So how does everyone get around this ? Do you unmask everything and then remask the windows with tape or film ? Or do you put it on the windows thicker to start with ? Does everyone use Nitro Block in a can or is there something else you all use ? I know Faskolor do their own one and I'm guessing for this question that would be better however I've never tested it's durability and wonder how it would come out against fuel ?
