Warming GRP repair

[mystymike]

Picked up this question whilst running through old index. When mains power is not available. Depending on the size of the area, warming can be achieved by using a couple of hot water bottles (rubber type) this amount of heat is sufficient to set off the curing process.
I have used a 100watt lamp powered by an inverter (with engine running) to effect curing just recently. A car halogen headlamp bulb can do the same from the 12v system. So long as these methods are fully supervised.

Yep, have used the hot water bottle method myself in the past - works fine.

Using an Infr-Red lamp does a better job of warming a GRP repair, but it must be supervised!

A real 'old hand' North German shipwright, accustomed to repairing in very cold weather, did a super repair for me by cutting the bottom out of a 2 litre antifouling tin, which he then used as a directional funnel to orientate the heat from his blowlamp, whose flame he varied to suit what he was dojng.
