Thank You...

It's certainly a nice way to go when you can just sand a primer nice and smooth or even polish it a bit, then polish your mould further when done. But you should just do your own small test sample with the primer and exact release system/technique etc to know for sure if it releases ok. Fastacraft Facebook page
