Hey there fellow Composite Nuts!

I have been making various parts however now i am needing to create a perfect flat panel with a perfect gloss finish... currently looking at various panels/sheets that will be strong enough not to warp or ripple at all and keep scratch free so that either a large fiber glass mold could be made from or infuse off directly.

What economical CHEAP ways do you guys go about obtaining this surface finish?

I have been looking at acrylic panels (although getting a large one isn't very cheap) and whilst writing this post i think later i will have a look at large mirrors.)

Cheers,
Dave.

Has anyone tried a 1/4" (6.35mm) Piece of polyethylene plastic? I was thinking of trying this. The piece of plastic is cheep enough and the resins will not stick. Just concerned with two things....1. will it give a good enough finish and will the Gum tape stick to it for vacuum infusion. Anyone have answers?  I really don't want to go buy a large piece of glass. I don't have a good place to put it when done.

Thanks,
