Looking good !

Repairing those little alligators will be easy, just grind out an neat shape and fill with gel coat with some wax additive or just tape a cup over the small repair to remove air while it drys, then get sanding, compounding and polishing.

If you are going to do and infusion without repairing the mould fill in the voids with release wax.

Looking forward to seeing the product Smile

Thanks so much! I was really hesitant to chisel out and/or try to sand all these superficial imperfections. I'm gonna scrape and fill as suggested.

Decided to put some work in on the mold. I pulled it out to the back yard for trimming:

And after trimming I moved it down to the basement...this is where I will be setting up the vacuum bagging and infusion:





There is one significant trouble spot where the chopped fibers did not completely support the gel coat...there is some undermining of the hole with tracking laterally. My thought is to mix up some gel coat and inject it into the cavity with a syringe...thoughts on this approach?

I would give that voided area a real good prodding with a rigid tool to see if it caves in. If still in one piece then I would try injecting the gelcoat. You've nothing to loose as if it fails, it will break off on the first use of the mould and you can then just do a conventional gelcoat repair.
