ok - another day in (my) zed shed
slightly different procedure this time as I think the red was picking up the grey primer - so after the grey I used silver, then the red and finally as before the clear coat.
a lot more careful on the rubbing down this time
results are looking better and by the time I finish all 4, I might actually be passabe at it
after 3 coats of grey primer
3 - 4 coats silver
1st coat of red
see how slowly I'm going this time
2nd coat of red
3rd coat of red
4th coat of red and fisnished with clear coat
still left some marks from rubbing down - I will get better
