Fibre glass repair temperature?

[JonC]

I need to wrap my stern tube with a bit of glass to make a watertight seal but with this weather which is to be expected at this time of year I’m thinking it’s too cold outside. What are my options? 
I could tent up a bit with a heater but I’m worried about condensation.

Suggestions please.

Fan heater might work?

For small patches add a bit more Catylyst (2% is usually best) and use a hair dryer to activate it.  A hot hair gun is too severe.

IThis is the area, from what I can work out the tube is bonded into the hull after the boat comes out of the mold. A few years ago I fingered some sikaflex around it but it appears to have come away around the top.

I plan to grind a strip about 25mm around it then layer a couple of strips of glass around it. 

Another concern is that the constant vibration may cause stress on the glass fibre, so I’m also considering grinding out a smaller band and using sika 292i on it.

that does not look good john is  it where the stern tube houseing comes though the boat has your cutlass bearing gone  i would be looking to be putting 7 to layers in a much bigger area than an inch away from that if that comes apart in the water you could end up loosing  bud   👍

I don’t think it’s that big a threat, the tube goes about 500mm through the keel, the cutlass bearing is fine and there is no play in any of it. The only issue is the water getting through.

6 to 7 layers over at least   good preparation work clean with acetone and you should be good to go mate
