Attaching it went well and I only had to push through the tapped holes with the clecos...no problem. Once it set up, that where the difficulty was. I removed all the clecos...some will need some clean-up to get them working properly again. With the clecos removed it did not budge...I thought I was hoping to have to leave it attached. I went ahead and drilled the remaining 2 holes. I ended up using my chip chaser to work it between the aluminum wing tip and the new fiberglass...that with a lot of prying on the formed wing tip and it eventually started to break free. I think I will try to release agent specific to fiberglass for the other wing tip. A little sanding and everything is ready to wire up and attach the light.

Once removed and cleaned out the clay...turned out well, but a challenge to remove
