    RE: Z-Poxy over Epoxy?

    Pacer Z-Poxy Finishing Resin (#PT40) is what I use for glassing hulls. Up to 1 hour working time and 3 hour cure. ( But I usually wait at least 24 hrs for anything I glass) I have had no problems with it over other epoxies.

    RE: Z-Poxy over Epoxy?

    Thank you Pro. I prefer the Z-Poxy over the Epoxy but at times I like to use the Epoxy for faster cure times.

    Thanks again....[sm=thumbup.gif][sm=thumbup.gif]

    RE: Z-Poxy over Epoxy?

    FYI.....Z-Poxy is epoxy, it's just a trade/brand name. PACER is the mfg. Besides CA adhesives, they also have epoxies in their line including 5 and 30 minute types.
    When it comes to surfacing resins, other than West Systems, the Pacer Z-Poxy is at the top. It's available in smaller sizes so you don't have to lay out a bunch of cash up front and then have it sit, unused.

    RE: Z-Poxy over Epoxy?

    If you ever want to speed up the cure a bit on epoxy, and definately polyester resins, then before mixing the hardener and resin, or resin and MEKP heat the up. This applies for polyester resins more than epoxy resins, get a blow dryer or similar air heater and heat the bottle of the resin and catalyst up, no heating when they are mixed, they will flash cure faster than you can say holy s**t. Since resins and hardeners use a chemical reaction to cure if you add heat you speed this reaction up.

    RE: Z-Poxy over Epoxy?

    With epoxy, I discovered that using a blow (hair) dryer on it makes it flow out better, especially when glassing. Not a lot of heat though. I used one of those defusers that come with most of them.

    Yes the hair dryer trick helps, first it thins it a bit without changing the chemical properties as with acetone, and heating it once applied is fine, but if you have mixed up 5oz of epoxy and you start to heat that you're asking for trouble if you don't know what you're doing. Epoxy itself can ignite if mixed in large batches, never mix more than a liter at once, and if the epoxy ever starts to turn black and smoke get it outside fast because it is on the verge of burning.

    That's how I do it. The surface that has just had the cloth and resin applied, is hit with the hair dryer to get it leveled out. This is a time saver when it comes to sanding, as it evens out the surface better than if just left it on its own.
