Ok, the Jodel is ready for some paint, the full size i am modelling it on is white with a blue cowl area which then curves, runs along the front of the wing and also into a stripe which runs down to the tail. Undecided whether to airbrush the whole airframe white then add the blue or leave the frame `oh natural` and just ad the blue, it is supposed to be a vintage build so maybe just the blue, opinions? I will be using Tamiya acrylic paint, the model is electric.

Also, will the masking (frog tape and a thin automotive mask tape) pull the finish off the surface? Final question, airbrush or good quality hand brush, what have you guys done with good results? Sorry for all the questions, very pleased with the model so far so want the finished item to look good. Decided against coloured tissue for the trim. This forum is great, had so much good advice during my last couple of builds yes img_20200705_103200_resized_20200705_105031314.jpg

My Lil Cub is covered in Polyspan, I used waterbased Floor Varnish rather than dope to seal the surface. The paint is hand brushed Dulux tester pots, though I airbrushed the tail surfaces, you be hard pressed to tell the difference. This was sealed with a water based matt varnish, hand brushed. You should be fine with frog tape. I would use the low tack version, a lot will depend on the paint you use, but I have had no bother maskinmg on other models

Lay down the tape then seal it by running a brushfull of clear dope or clear acrylic along the edge, it will stop the colour creeping under. If the colour trim is a small area, ie a narrow trim strip, I'd just brush it in, much quicker all round.
