Once again this makes me wonder why my slow build airplane is stil= l=20 holding together.

I never did use "cap strips."

The process was

Clean wax/oil with an EPA disapproved (and now unavailable) paint=20 thinner

Clean with acetone using white lint free paper towels and lots of=20 them

Sand with a grit large enough to roughen, small enough to not cut thru=20 fibers

Clean with acetone using white lint free paper towels and lots of=20 them

perform one of the steps of joint closure with industrial cement (= now=20 Hysol) or flox and/or BID.

Repeat

Just remember that the crucial part of making something stick together=20= is=20 that it must be CLEAN and ROUGH (or ROUGH and CLEAN) before the adhesive is=20 applied. Don't forget to take the plastic off the multi-BID layups!

650 hours and I am still waiting for the first delamination! =20 Anywhere! My main gear over center link pivot bolt support block is st= ill=20 attached to the main spar cap even after many hard landings.
