So wax "dulls" down the slippery surface a bit making it easier to get the gelcoat on.As Fasta mentioned it is also good insurance to use 2 release agents like that. We especially recommend it for taking moulds from patterns where you only get one chance. PVA is even safer chance of release but it leaves surface marring meaning you need to polish the mould a fair bit to get a good surface.I'm quite new to semi permanents (Zyvax) and I have been giving the mold a single coat top up after each pull...as much as because I will lose the Zyvax to age as anything. You would need to do a full clean of the mold to apply more semi permanent I assume...but imagine wax coats would give it longer life?

You can even change the release/slip with the different grades from Zyvax/Chemtrend.

If you wanted to add more semi permanent to the base coats under the wax then safest you should start over with cleaners etc or even a fresh cut polish, new semi permanent 5-6 coats and then wax 5-6 coats initially.
