Treat it as a learning exercise, we all start somewhere, and we've all Flamingo'd up paint jobs in the past (yes we have lads).
Haha, we have indeed! I still need to redo the paint job on the holding bracket
for the Raystorm blocks for HELIOS. I put on too thick a coat of paint (well, several)
and it was all nice and good until I tried to put the brackets back on the blocks
again, and woops, the close fit between the block and the bracket did not leave
enough room for my paint coat and ripped it off in parts. Ah well, I'll sand it down
and redo it, such is life.
Don't feel too bad mate, sh!it happens (or is happened, from time to time

),
the most important part you have already done: You've realized you corked up and
are intending to fix your mistakes in the future.
And whenever you feel bad about screwing up, just remember that a technician once
forgot to mention to anyone that he had removed the bolts securing a satellite to
its platform and when his fellow workers started to tip the platform the satellite fell
over and got banged up to the tune of 135 million USD.

Imagine putting that on your resume... :lol:
