Thanks Colorado. I pondered how to do the 3 row rivet detail for the panel borders of the on this car. Read the recommendations on relevant forum posts. Archer rivet decals are a thought but expensive. I got a rivet tool but the thinest styrene I could find was still too thick to reveal the rivet detail. I experimented with aluminum foil and that is better but cutting it exactly is beyond my ability. Model filler. I will ask my LHS if they have that. If I get reasonable results on this car I have 2 other projects in mind that involve filling in windows. Appreciate your advice.
