Don't crush them.  I use thin CA for capstripping.  I put the forward end in place, CA it, and then run the strip down along the rib with my fingers with the capstripping side down so I can drizzle a LIGHT  drop of CA to the rib and strip.  Ya don't need much, as you'll see the glue wick along the strip for a long distance.
Yes, you will get some glue on your fingers.  Yes, you might very well glue you to the wing, but no, it ain't permanent and yes, you can (carefully) get loose.  Have fun with it, and keep in mind that the better the strips fit the leading and trailing edges the lighter and nicer the wing will be.  Take your time in fitting the length of the strips.

The cheap one-use plastic gloves like the Subway sandwich people wear don't stick to ca glue.  I got mine from the dollar store. They are great for holding pieces that you are spray painting, too.

I use Elmers white glue almost everywhere when building a model with just a few exceptions and this is one of them.  Cut your cap strips one at a time to fit.  I use thick CA and run it lightly along the top of the rib.  Then place your cap strip on the center of the rib and hold down for a few seconds using very minimum pressure till the CA kicks.  I have broken ribs in half by pressing down too hard and this makes me say dirty words.

In free flight models, when we still used to glue the carbon cap strips to the balsa ribs, we used clear sellotape to hold the strip to put&hold it in place. Very easy and no mess with glue!
It's no longer used in serious FF but works well with all-balsa construction.
