I have been making some plaster molds and i heard i need a sealant to keep the worm from sticking to the mold and create a semi-gloss finish. So What sealant do i need?

Hey Nick, I use Mog-Pog on mine. Let it dry very well and you'll be good to go.

Cedar1, where would i get this?

You can get it at any craft store

is the mod podge just the regular mod podge or something special?  I bought some of the regular stuff, but  I'm just not sure if it's right.  There were like 10 kinds at the craft store I went to and the fella helping me looked like he'd be much more comfortable picking out pink lace than helping a fisherman.

Wait... heres what this bass resource article says...

"Sealer - any plaster/wall board, water soluble sealer such as Valspar® gloss glaze (superior in many respects to Mod-Podge® craft glue, which peels off after 10 pours.)"

The store I get mine at only has one kind so I really can't be of any help or even tell you what it is other than Mog- Pog

Home Depot or Lowe's sells Valspar and it lasts much longer than Mod Podge. It comes in a paint can and is water soluble (for cleaning paint brushes and thinning). It gives a nice hard glossy finish that lasts for a year.

The other surface finish some have used is 2-part Devcon epoxy, which lasts forever, but which is harder to use.
