Hi, I have had a go at modelling again after 40 old years after picking up a model from Aldi - Hunting Percival Jet Provost T4 starter kit. I have gave model 3 coats of acrylic (brushed on) last coat was in the morning then in the evening I gave the model a coat of Humbrol Clear Gloss. This morning I had a look at model and there are loads of white cloudy milky areas all over the model - any advice please where or what I have done wrong?
