Technical Paint Question

[BSARGS650]

Why is it after careful preparation, cleanliness, attention to final top coat, etc... that a slightest knock results in a chip to the finished component, yet, if a drip gets on a dusty concrete floor, it needs to be removed with a chisel when it has dried?

 You could be onto something there- concrete tanks...make a mould and precast 'em

Many thanks duTch for your suggestion - tried it, but, it was a bugger to get the machine on the stand, didn't go so fast, and lots of complaints from the rivet counters.........
