Vac Bagging

I was wondering how to achieve a smooth surface when hulls are manufactured using the vac bagging technique. When I have experimented with vac bagging I always get creases and a slight surface roughness?
Many thanks

Use a bag with very high elasticity, the correct perforation on your release film, and a breather fabric to smooth it out. Be sure to lay the glass down nicely by hand, and if you are using the correct bag, it will have to be sucked into the mold, so there won't be any creases. Fi you really want to go the cutting edge, you can use the infusion process. Bag your material dry, once you like the way it sits, allow the vacuum to suck in the resin. Pretty cool stuff!
