Last night i was about to start cutting the cloth to the size and shape needed. Upon final inspection of the foam plug/mold i noticed gaps between the foam and upper parts of exhaust nozzles. I used light weight Spackle on there to fill the gaps and build if up for smooth fabrication. Sorry no pictures of this step. I will see how it dried up and if it needs more filler build up i will do it.
I want to give full credit to my friend Mike Emilio for introducing me to this great filler while we were working on my Super Connie model. If it wasn't for him, im sure i would have been using some other filler that would have been on heavier side the light weight Spackle!..
Very much appreciated Mike, Thanks Man!!....
