Which types of applications are you referring to? Which applications would you consider pva release agent appropriate? Edited 7 Years Ago by k.alan.bates

Which types of applications are you referring to? Which applications would you consider pva release agent appropriate? If you can spray the PVA then you will get a pretty smooth finish (but not glossy) and it is quick to apply. For a glossy finish (assuming that your mould is glossy) you need to use either a wax or a liquid release agent that you can buff. As mentioned above, moving cloth around on PVA can cause it to lift (as it forms a very thin peelable sheet) so you have to be accurate with your first placement Edited 7 Years Ago by Steve Broad

would vinylester molds work the same as poly molds or should this work?

Vinyl ester moulds should be perfect, provided you are using them within their temperature range (ie. not using epoxy pre-pregs over 100C).

awesome! I was planning on making some smaller parts with infusion but wanted to play around with some prepreg on it too.

If you're planning on using X-Preg from Easy Composites, it does work with a vinyl ester mould but you will get some pinholes. It's not awful, but it's not perfect either. For epoxy infusion - vinyl...

PVA is great for applications where you aren't sure about material compatibility. I use it for virtually every mould I produce off an original that I cant modify or respray with coatings I know wont....
