Fiberglass Supply Depot PARTALL® Paste #2 Mold Release Wax -12oz can

Value for money, works well...

I have used this brand wax before, in making molds, from plugs, as well as molding parts out of fiberglass. My molds are generally polyester, resin as it is less expensive. The parts I choose to mold are usually made of epoxy resin. You can use the wax for either or. Make sure you have an ample layer of wax, that is coats, for your plug, to enable separation. The same for your mold, and the first time you use your mold, more coats than normal until the mold is seasoned. I also spray on an alcohol water-based PVA once the mold is wax. This helps with the release. Then I use compresses air for the separation of the part molded, to the plug.

This works well. Follow the instructions. I use it on shaped wood I am about to use as a mold for fiberglass.

Pretty gummy stuff to work with but did the job on releasing parts coated after applying epoxy.

Using for laying up fiberglass in a tub shape. Used 3 layers and rubbed into surface with a shop towel. Would have given it 5 stars if it pulled out like butter. Works pretty well. Could supplement this with a vinyl type paint on release agent.

i was unsure at first but this product is amazing did exactly what it says it will do and i didnt even need to second step the release with pva

I like using this as a mold release. I often spray PVA on top just to make sure I get complete coverage. I don't have any problems getting parts to release from the mold.

So far product has been working great.

Compatible with PVA and that's what I needed
