Group: Forum Members Posts: 7, Visits: 31	Hi guys, I plan to do a resin infusion as follows: (top to bottom) bagging film (from starter pack) 160g twill weave 390g twill weave closed cell foam 390g twill weave 160g twill weave flat acrylic mould (perspex) As this is first time I'm going to do this I'm worried if the finished product will be shiny, smooth and glossy on both sides? Or I am missing something here? Thank you

There's a thing with the plexiglass, perspex, pmma,... :p that could cause a problem... I've once did an infusion on a flat piece of plexiglass, Due to the resin getting hot when reacting it melted the plexiglass into the piece, making it a difficult to remove even with the mouldrelease applied on it, had to remove it with a heatgun... But just like robsk1 says just do some testsamples to see how it works for you, maybe I just had some good/bad luck with the closed cell foam and plexiglass. good luck!
