I put the big felt pad on a 10.8v dremel and powered that thing up to about 5 (10 being the highest). While pressing in from the insdie part of the windshield I rolled the tip around the break. Surprisingly enough it filled those tight legs. I will try more tomorrow and post the findings.
Thanks so much for this tip!

Are you sure the legs filled with resin or did they close due to expansion?

Becareful to not generate to much heat with the dremel(friction) or any source for that matter as this could close off the legs prematurely providing a false sense of fill. Especially tight fractures. Just something to consider.
