certainly not if you leave it in the cup! its an exothermic reaction so it will cure faster in a cup as it self heats.

thanks for all the replies - looks like the oven is a good idea. We've got high routes affected by snow today so I don't think we're going to hit 20degrees any time soon!

The boat's booked in to get the new engine fitted on Easter Monday, and the console needs to be on by then, so I can't afford to wait for 'mother nature' to warm up the shed...

I'm waiting for the colour matched 'flowcoat' to come up the road (hopefully it'll get here today) but it occurs to me that I need to check whether it has the wax added. Never thought to ask.

thanks again.

If it's called flow coat, it should. If it's called gel coat, it shouldn't.

Thought I was cracking up reading others comments.
All flow coat is is gel coat with wax added.

It will if you buy it pre-formulated but we, as builders, knock up our own from resin & gel/pigment, hence the need to mix in the wax.

So you're not buying flowcoat then - you're making it by adding wax to gelcoat?

If you buy flow coat from the likes of cfs or ecfs then all you will need to add is the catalyst. If its clear flowcoat then a pigment too, simple.

checked this afternoon, and in my case at least it's the 'simple' option.

It's coming up the road as a gallon of pre-prepared and colour matched 'flowcoat' with no need to add wax, just the catalyst.

With any luck I'll get it tomorrow or Monday and get a shot of the oven some time next week.

In the glassing I've been doing I've been mixing in the catalyst at somewhere between 2 and 3%, which seems to have been setting ok. For flowcoat (at 20-25 degrees C) would the same % be OK?

It tells you on the instructions.
Not sure if it varies between companies?

I could do with flowcoating my hull but have been told that it could sag off the hull due to the cold? Is there any kind of primer that can help with this or am I going to have to wait for the warm weather of August the 19th, around 2 o'clock till 2:30?
