How do you get 'Not gone off' Epoxy off
Tug-Kenny RIP:
Says it all really.
Yesterday I mixed the two bottle epoxy to secure the hand rail to the fibreglass bow and taped it down.
This morning it's the same consistency as when it was made. The temperature in the Garage is 4 degrees C at the moment but was probably that or less during the night. It was old stock from last year.
I peeled off the tape and have lifted the rail (with rubber gloves on) and the stuff is running slowly down the hull and is still on the back of the rail.
My question is 'What chemical can I use' to remove all traces please, and will a new mix adhere satisfactory to any residue ?. <:(

Answer in two parts:
1) the solvent for Epoxy (uncured) is pretty near any solvent. Alcohol (meths) is porbably the easiest, but acetone, cellulose thinners and lots of others should work
2) given the temperature in your garage the Epoxy is just waiting to cure. all chemical reactions double in speed (we used to be told) for a 10degree rise in temperature (cant remember C or F :(()
so mop off what you don't want with solvent and warm the whole boat to a very warm room temperature and she should set happliy

Tug-Kenny RIP:
Thank you the info Andrew.
I tackled it today and you're right. It is runny and tacky. I just kept wiping away and it cleaned up reasonable.
As it's an isolated section and I won't need to go there for a while, I shall leave it be and let it dry. I went down and read the can and it said it must be 70 degrees F to cure. Must wait for the summer.
I've continued my blog on the Gry Maritha page and have photographed it.
Hey Ho, thank goodness for Model Boat Mayhem. :-))

Use a hairdryer on it at low setting Ken.

Ken,
glad the solvent worked
Colin is of course dead right - a little applied warmth will do the trick.
My habit is to use a moskito killer (the hot plates that you used to put pellets on) and place the boat over it and then cover all with a big cardboard box, Its only a few watts but it raises the temperature enough to speed the cure
- other folk use a 40W incandescent buld carefully placed as a heater
