I did a pretty large priming job, tacking the spars and all the wing ribs. I did follow all the recommended steps for priming to see if I will get better results then the priming I did in the empennage:
- scratch all the parts with a scotchbrite
- rinse all the parts
- clean all part with acetone
- brush all the parts with alumiprep
- rinse all the parts
- clean all part with acetone
- Prime
The result looks good, I tried to peal by hand the primer of one of the ribs and I did not succeed.
