This is the solution I came up with not wanting to use tape or buy a product to use. The caps I used are Vortex and they went on a Vortex scope, the objective cap fits very snug but the cap for the eye bell was quite loose and required two hands to open. First I decided to build up some material for the cap to fit over a little more tightly, for this I used a .5" wide Ranger Band. The cap was still a two hand cap... so I added a second band roughly 1.25" wide and rolled the band starting at the back and rolling it towards the Objective lense until I had clearance for the rubber sleeve on my Vortex cap. Then once positioned where you want the cap just roll the band back over the rubber sleeve. It's not the most beautiful repair and it's not hidden like tape is however it is very solid and worked well for my needs. Hope this helps at least one other person. :)

Update:
I have since added one of these to the objective end since the addition of a sunshade also provided a loose fit. I also went back and cleaned up the edges on my original band and turned both bands inside out to hide the mold marks. Just figured I would share in case anyone was wondering if this would work for an objective lense. I also had a problem with the eye bell flip cap spanking the scope(don't worry it likes it) every time i opened it so I put a small cone shaped rubber foot for an old aquarium air pump under the band which almost completely silenced the cap.
