I just striped a jet with a glass fuse and wings with acetone, it worked great. I soaked some rags with acetone and laid them over the fuse keeping the rags wet at all times (the rags keep the acetone on the model at all times). After about tem minutes the clear coat started coming off. The paint and clear coat that was on the model was PPG car
paint and it came off no problem. Laquare thinner works just as good. Sanding if done incorrectly can leave gouges and marks that you will have to go back and fill and sand. So I vote for chemicals. PS my wife complained about the smell. I learned this method through making mistakes when I was painting a model and had to start over several times because I was just learning how to paint.
