Just like to ask where can I buy wax in xylene in Queensland Australia,
It is wax in xylene; next question? what kind of wax, how much wax??
just wondering if anyone in Queensland new where i could buy this additive,so my epoxy filler coat is better and can sand my boards the next day…
try paraffin. wonder if there might also be some other volatile in addition to xylene, drier, something to help the wax disperse etc…
whatever the real recipe, a few cc of xylene did a good job reviving my dried up Additive F in the past.
I considered trying Herb Spitzer’s recipe from years ago but never did.

Heat-up the wax in a pan.You don’t need a complete meltdown but make it soft and don’t burn it.
After that, just stick it in the xylene…It will take overnight to get a mix.You can agitate it to speed up the process.The mix is 90% xylene ,10% parafin wax…roughly.Herb
Don’t put anything in it…especially wax. If it’s crappy epoxy nothing will help it, but if it’s surfboard epoxy like resin research etc, then all you need to do is heat it up in the micro for about 15 seconds. I stop using additive f years ago. Only heat up the a side, not the hardener side.
Now if you are having a hard time flowing out your hot coats or getting fisheye, blems or zits, then it’s all in your process. Chemicals will never trump a clean prep sanded lam coat.
Work fast, clean, efficient … Then walk away and let it level out…just walk away…walk…walk away… Put the brush down…and walk away.
What ever you do not put wax or some other kind homemade bullshit in your epoxy.
Resinhead is right, no need for additives if you’ve done everything right . Don’t blow off your board with air that’s not filtered through an inline oil filter , don’t sand with stearated abrasives prior to your hotcoat , minimize the contact of your sweaty, oily hands to the board . Common sense stuff to eliminate the drama
Addf purpose is mostly the same as styr P in poly : isolate surface from air. Epoxy hardener can react with water in air to make blush in surface, sanding nightmare. Hard cure blush free époxy is well sandable with appropriate tech. In hot dry climate good quality surf époxy don’t blush. If you doubt you can water scrub to remove blush before sand.
Thankyou everyone for the replies,feel bit better about doing hotcoat in epoxy now…funny glassed maybe 20000 boards in polyester.in epoxy about 6 boards…keen to play with some carbon fibre rail frame for personal boards…something different…will post
If you don’t find wax in xylène you van use styr p instead. I know some do with it for sanding résin. An alternative is poly as finish coat on époxy. It work far better than what you van read here and there an i know many pro that do it in big quantities without problems. Just let your lam fully cure then scuff it well.
