Preparation of the foam ribs.

Setup for the trailing edge sealing:
Matchdrilled an aluminum angle and an aluminum bar for both trailing edges. Putting the trailing edge between the aluminium angle and the aluminum bar and using clecos in all holes keeps the trailing edge straight avoiding putting weights on the structure. Important to correctly position the aluminum angle so that the trailing edge is in contact with the inside of the aluminum angle. The aluminum bar is then checked on top keeping the two skins ""sandwiched"" and with constant pressure.

Applying the sealant with the syringe is pretty straight forward, you need only to pay attention to avoid touching too many things with the dirty gloves or tools....acetone cleans up the sealant pretty well.

After sealant is cured removing the angle and the bar is pretty tough as the sealant excess bonds the aluminum, however using a long blade and some patience and strong pulling it is relatively to separate the whole assembly

Thanks Lucio for the suggestion....

Cleaned all the holes and removed the excess with some acetone
Trailing edge look extremely straight
