PVA or Wax release agent?

Chaps

I'm nearly ready to start moulding my new bonnet plug, and while I've made all bodywork, it wasn't in the traditional method (ally/mdf and vaseline).

My new bonnet will be made in the traditional way so I need to get the bonnet to a near perfect polished finish before waxing/pva ing.

What have you used/would you recommend. Mould, fwiw, will probably be in a good few pieces all screwed together.

Want to order tomorrow

Thanks

Simon

Both is best, plenty of coats of wax, polished, then PVA on top

I finish the `plug` with a coat of poyester spray filler (well thinned with acetone) and then a couple of coats of `mirrorglaze` wax . This gives a very fine satin finish to the mold which can then be polished for a good gloss finish .

I've used colron furniture polish recently. Just make sure it's the silicone free type. Lots and lots of this and then a really good pva. I've also got some Chemlease 131 but haven't had as much joy with that.

3-5 coats of mold release wax should be sufficient , if you use PVA that can dull it requiring more work and also water/blue marks that take for ages to polish out .

I found several coats of wax was fine and so long as it was well polished gave a really good finish....

Bit slow on the gratification, but

Cheers Chaps

Wax on it's way, CFS didn't have any PVA so that sorted that out
