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

Perhaps sealer has enough slip to make PVA fisheye (one that i use from Chemtrend makes sourface quite slippery on its own) . You could apply some wax befor pva or/and if you have the means PVA can be sprayed.

For moulds i always go wax/pva route. If applied nicely there isnt much to correct afterwards but its hassel free when it comes to release
