I spent about 10 years building car models. The hard part was trying to create a flawless paint job. Eliminating or covering over little specks of dust/dirt was always a tedious chore!
Now that I'm building armor it's almost the exact opposite. If something 'gets' into the finish I just try 'go with it' and let it be a part of the 'weathering'! If nothing else, this way is sure alot less stressful! So in other words "go with the flow"! This is a long way of saying I agree with Robert!
