Any tips on releasing a long mold from the plug?

Usually the plug is destroyed after one pull unless you want to make several molds from the same plug for series production. One mold is good for 25-45 pulls before repair is becoming a headache.

Me, if all else fail and the mold is somehow stuck to the plug, I would use a rubber mallet and give the mold a good whack. Works everytime. The mold at this point is flexible and it is the plug that would most likely be dimpled. I don't care. It will be destroyed anyway. Plugs are useless to store. I don't overdo the plug. It is usually lots of plaster patches and Bondo.

 

Just an update that both deck and hull released very easy. Especially the hull, I used just one plastic wedge and with a little bit of air and lift it came all out super easy.
