I have a big plug I'm ready to mould. After so many failures with easy lease I was going to use pva.  The plug is sealed with s120 and has a clean smooth finish. When I apply pva though it fisheyes like its a wax resist crayon picture and I get bad patchy coverage.  Is there something anyone can recommend to prepare the surface for pva application?  I always pre clean with EC mould cleaner so it should be contaminant free...thanks

Thanks guys, the recent hot weather has allowed me to make the gelcoat touch up outside quite nicely so im on with the sanding now. Once done I need to make two mould flanges as this piece will be made in two halves and bonded together.  Appreciate the advice, thank you! 😉
