Paint in Composite Wing Hinge lines..how to remove??
Hello Experts, Ineed your wisdom!
Irecently had an all-composite jet painted. When Igot it it was gelcoat white, and I had it primered and painted with PPG. My problem is, now, after painting, the paint settled in the "live" hinge lines that were cut by the fatory and now I have two issues: 1. The control surfaces are stiff. 2. The paint will eventually crack and peel from these hi-flex areas. Question:What is the best way to carefully and accurately remove the paint from these areas?My idea was to set up a jig and use a straight edge and a Dremel tool with the router base to rout the paint out. However, I'm hesitant to get a Dremel tool so close to this wing, for fear of damage. Is there a better, SMARTERway? Thanks in advance!! |

I would 600 wet sand it away. Very carefully.
If it is very thick use 400. And don't use that guy again. Steve |

You might try a triangle file with a fine tooth to it. And carefully file out the paint but dont cut into the kevlar/nylon hinge material. This is typically how you manually create live hinges in a diy kevlar live hinge layup.

dbsonic has got it right. Clean it out with a triangle file.

You might want to scribe a line before hitting it with the file.
