I am going to take your advice on the pva instead of duratech.

Don't do that, Josh. Use the PVA after you wax your mold, but before you apply the Duratech that makes the surface of your part. PVA is a water based mold release that forms a plastic film between the mold and the part. You have to spray it on, preferably at about 60 psi so it mists.
I see in your second pic another possible source of alligators. Looks like you used modeling clay to fillet your inside corners. I learned that from strick, and it works like a charm. But, the oil in the clay can mix with the resin in the Duratech and cause it to alligator, so again, the PVA is important. If you spray the mold with PVA after you complete your clay fillets, it will seal in the oil and protect against alligators.
