Patching large rigging tube hole.
This is something I have wanted to do and Ihad to take my back seat out today so I started on the patch. I glassed in a small piece of honeycomb composite to the underside and built up the glass then faired with P77. Looks great but I have one question before a spray the gel.
In the past when I have done this, awhile later I get a little shrinkage and an outline of the repair that has to be re-sanded and buffed. I assumed its the filler shrinking a bit over time. Should I wait a couple weeks before gel coating?

PC 7 may not be a good filler to use under gell since gell is poly and has a very hi solvent content, and pc-7 is epoxy. Spray it and let sit. If it raises the filler edges, it may be solvent attacking the epoxy. I always used paint to finish epoxy surfaces.

P-77 polyester filler and fairing compound offers the user a smooth workable paste with a set-fast cure to expedite those applications for repair or finish.
its not worth the money.

Sorry for the mix up on products. I have had very poor results with the adtech p-77 myself. Every place I used it on a boat, bubbled up under the paint later and had to be repaired. Will never use it again......

Its hard to tell but its built up underneath. Coring with two layers of glass then cut circle of glass to fill in the hole then overlapped on top. I beat on it pretty good making sure it as strong enough because thats right where I get on and off the boat in the water. I actually put me knee in the middle of it and bounced up and down.
Between the glass and the coring I used under it its probably 3/4" thick. There are two layers overlapping on top.13' Biel tunnel AKA "Flight Risk"

That's should work. I all ways taper my repairs trying to us multiple layers of glass and never a issue . If accessible from underneath I will put a few layers for extra strength
