Ooooops! sorry Sassy but you have obviously had a long, bad day. I actually for your interest have had Creative training and more, and I thought that this site was to ask questions to more experienced technicians and get answers from whoever is wanting to answer NICELY. You don't have to answer threads if you don't want to, and as you are so cross and rude you really shouldn't answer. I do however agree with you about me not answering threads, but I didn't think that this was a must at this stage of my knowledge. I read alot on here and have learnt alot from mostly nice people and I have thanked them all for their help. The reason I was asking the question about two different resins and systems, is that I am booked and waiting to go on a Fabric# course as I was having teething problems with the MTW, so I thought until that time, I would go back to my old system, but wondered whether I could mix them, as I know the Boost is a very strong resin to end with. I am not a Free Rider as you call me and have spent alot of money on various courses, but I am still learning and it is still early days for me, I am keen to learn but cannot get on this course tomorrow, so please get of your high horse and learn how to speak to people. You are enough to put anyone off asking any questions on this site, again I do apologise for not participating in any other threads but as I said, the majority on here probably have had years experience to my months.
