Is the plastic from Delmart good for senkos or do you have to add alot of softner or hardener. Any suggestions on molds and from where because the one from lurecraft is a too skinny and has a flat side.  

I purchaesed a starter kit form Dels and the plastic is calhouns, high quality and you cant beat the quality of his molds.  The stiffnes is just right and you can always add a teaspoon or 2 of hardner or softner to get your desired hardness.

Buy from Delmart you wont be sorry.

I also bought all my stuff from del.  he has a senko formula on his site.  It is almost exact.
