Both are OK with fibreglass, epoxy is better with carbon.
Only epoxy with styrene foam!!!!

Also if they haven't completely cured it's not good to mix them, one stops the other from setting. (not sure which way round)

Polyester is harder but more brittle, epoxy is a bit softer but much tougher.

What decrepit said, also to add on, don't use rapid set epoxy in larger quantities on polyester/vinleyester resin surfaces, it heats up more than enough to re-soften the polyester, i discovered this the hard way

^^^ nup. FIVE of them had no idea

Go in and ask for speedfile sheets, epoxy resin, or geez even a M6x40 socket head capscrew and they look like they will cry.

I don't know why but when I'm at bunnings people ask me for advice. Mark at a guess i would have to say your a fitter as i believe there the only people who actually call them socket headed cap screws like they are

I had to describe what a pop rivet was.
sheesh.

I hate it when they say "Certainly, they're just over here" and I think awesome...
Then when I ask for the washer and nut to suit they say "No, dont sell those"

I hear ya brother!
My local Bunnings has hundreds of 20mm pressure polypipe fittings but exactly zero matching polypipe! (and apparently hasn't had any for some time, with no idea if/when they may stock some more)

I went in recently looking for some metal sheathed washing machine hose to stop my pipes banging.

I asked the guy where it was, he said "That won't stop the banging". I said "I know it will, as the banging stops when I turn the tap off at the wall". He flat out refused to tell me where it was, as he thought it wouldn't solve the problem.

So I eventually found what I was after, installed it, and bingo no more pipe banging.

I still give him the evil eye whenever I see him [}:)]

Yeah,I know,
back in my day when you went to a service station they ran out and filled it up for you.
Now the lazy mongrels just sit behind the cash registers.I mean ,its called a SERVICE station for a reason,,but now days you dont get any service.
I think I might write a letter to the government.



Oh stop ya whinging old boys.lol

Bunnings sell things cheap by paying 18 year olds , that have no building experience , next to nothing.
If they paid $60 an hour ,then they would get older experienced tradies that know a bit.
but then your rivits would cost $5 each.

As for Dick Smiths not selling resistors, caps, diodes etc,
they werent making money out of them anymore as most electronic stuff these days is not repairable, throw away, or all those bits are all inside one little chip the size of your thumb instead of a large circuit board.

I use to rewind pool pump motors for work, but its now cheaper to go buy a new one.
Such is life.

Ha! Ive had a similar situation Nebs, thats exactly why I keep it short n sweet. Usually I just ask where to find what Im after and don't let em get into the nitty gritty of what I want it for.
