fleece?

Iyes..I totally agree. and sometimes the stuff sits on shelves forever until it is used..not many know that resin has a shelf life..it might work if it's old..and it might not..not worth the risk for a few dollars more..and sometimes you might even pay more for inferior product..it happens.

The last batch I got I needed in a pinch so I went to a "chain" autoparts store. Well apparently the resin was a return because the tube of hardener was missing...but I have plenty so I opened the can and like the whole top 1/3rd was hard...that tells me some genius opened the can..dumped the whole tube of hardner in it..and then retuned it.

Now another good source for resin is Select Products..I don't just say this because I used to work there..the stuff is date coded and they even have "bubble gum" scented resin which is good if you glass in an area where people complain about the smell..I love the smell and the fact that it bothers everyone else..but sometimes you have to bend a little. And thier prices, at least for resin..are competitive.

Ah the shelf life of resin.  Who hasn't learned that lesson by soaking a project in cheap resin only to have it not cure.   I remember using that stuff  and my first batch would start to gel in about 30 min.  The next batch I would mix the same way and it would gel in 10, WTF?  And within 5 min after that, its rock hard.  I'll never buy that crap again.

Hey master, that dude that returned the resin is lucky it didn't catch on fire with how quickly that mast've started catalyzing and heating up. 

Yeah that can must have been piping hot for some time...what probably happened is the idiot thought he could just pour the entire hardner in and then he wouldn't have to bother measuring.

Guess he found out it doesn't work that way. And I was wized because that was the only can the store had so I returned it and had to use some old resin I had..I hate using old resin..well I can tell you know why. Don't use resin from a dusty can..lol.

I personally prefer grill cloth over fleece.  IMO fleece soaks up huge quantities of the expensive resin for no structural advantage over grill cloth.  I would MUCH rather put that resin into layers of fiberglass mat where it will make the most difference. 

For a tip, I ran into a product at a local boat shop that was awesome.  It is a UV curing resin.  You have no time crunch to beat the resin gelling on you, and any you don't use you can just pour back into the bucket (make sure nothings in it).  Once you are done, just take it outside in the sun and it hardens in about 5 minutes (longer on cloudy days).  The only other place I've been able to find something similar is here: http://surfsource.net/suncure/index.htm/resin.html  Although I have never used the stuff at that link.  For projects that you can't take outside, you will need a UV-B light.  They are pretty expensive.
