Patience is a must in modelling H - no patience = a messed up model. Regarding the vac formed canopy - you'll find that acrylic paints will not adhere very well, if at all, to vac formed parts, as they don't have the 'keying' qualities of enamels, or the covering power for brush application. They're fine for spraying, but absolute cr@p for brushing, without having a much less than perfect finish.
First, mask the canopy, using tape at least for the frame edges, as masking fluids will not give a sharply defined edge, and can, and will 'shrink back' as it dries. Once masked, if you have to use acrylics, then give the areas to be painted a primer coat, using enamels and let this thoroughly dry before applying the colour(s).
Alternatively, and this might prove easier overall, make the frames using painted strips of clear 'Sellotape' ('Scotch' tape I think, in the USA), laid into place and carefully rubbed down. If required, these can be sealed with a clear coat, and touched in, when dry and set, with a matt clear coat.
