Greetings! Newbie here...
I bought the beginners laminating kit which included the PVA release agent. The mould tool was made from Polystyrene with a wooden support, painted with (car) cellulose paint (thoroughly cured). I did wot it said for the release agent, but it didn't release. Sob, sniff. The paint came away in chunks. Wot a mess.....
Any ideas of what I did wrong? Be kind.....
Should I be using the wax release agent? If so, why is there PVA release agent in the kit?
I'm about to start reworking the tool for another go and would prefer to get it right this time!!
For scale, the finished parts are about 150mm amd 100mm long.
TIA

If you can spray the PVA, then you can build up layers and you can release off virtually anything. If you don't have equipment to spray, have a look at Preval sprayers. They will work very well for applying PVA.
