Hi guys iv been using the xcr resin and fast harder. ,  as I'm only skinning parts is there a faster setting resin I can use. ?  I still want the crystal clear of the xcr but with like a 30min cure time.between coats. 

Cheers

Yeah .. "lightning fast"  - and exothermal in the pot ... Wow ---  even a few cm's in the bottom of a plastic cup will melt the cup and go black-brown very quickly -- Blink

 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" --
