The fastest resin we do is our Rapid Repair which cures in 2 hours but it is no where near as clear nor offers the same UV resistance as XCR.

Since pot-life and cure time are inextricably linked, if you wanted a 30 min cure time then you'd be down at only a minute or so of pot-life which I don't think would be practical for skinning! Your best option would be to use the XCR skinning resin (which performs better for skinning than any other resin) and then use an oven at a modest temperature to accelerate the cure after application. You might need to experiment with your process slightly though (temperature of the oven for example) because the viscosity of the resin will reduce at elevated temperature and so you might find that the resin runs off more when it's heated in the oven. If you're only skinning small parts and you take time to work out what temperature you can get away with (you'll need to be spot-on with your timings) then this can speed your skinning time considerably.

"lightning fast" - and exothermal in the pot ... --- even a few cm's in the bottom of a plastic cup will melt the cup and go black-brown very quickly -- I've successfully cured XCR skinned parts at around 60 Deg. C. That gets it to the tacky but firm state in less than 1 hour total Process is as follows: Skin as you like, then leave until the resin in left your mixing pot starts to gel - this will be less than 30 mins .. Then put your part in a preheated oven at 50 - 60 degrees -- for about another 30 mins .. - check at intervals and then go for the next layer of XCR .. Leaving it at room temp. until it starts to gel avoids problems with the resin getting too "runny" -- "Sapere Aude"... Dare to KNOW! The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind... 103% of all people do not understand statistics... Do not adjust our mind, theres a fault in reality :-)
