any one does vacuum infusion with polyester, i dont have epoxy at my contry and i do overlay with polyester and its working very good so i tried to go a step ahead and i bought everything from ec and i do the same steps , but i keep facing bubles ????
as for overlaying , you can watch my channel videos its perfect

you can get a slow cure thin polyester to vac but you need to tap the pressure at about - 8 psi due to the stiren content
