Hi Palle,
Can't really help with the timing, I've only used epoxy in summertime, or not in winter. But the tent is an easy one. For inside a garage, a simple rigid pvc piping frame will do fine covered by a double or triple layer of the clear plastic used for growing tunnels. If it's just for keeping heat around the hull, have it about a foot (30cm) out each side of the hull and it can be the same above the hull. A series of incandescent lights beneath the hull will keep the enclose volume quite warm. A simple box shaped tent will work. If you gang the lights in 5 lights per switch, you can control how hot it gets. I think less than 2000 watts worth will do.

5 uprights per side, an elbow joiner on each and 5 pieces for the 'roof'. Lengthwise pipes can be tied or duck taped to these as stringers. A few diagonal pieces will make it less wobbly. Drape the doubled plastic over the frame over the hull. If you want more insulation, light blankets could be added.

I thought I had drawings for one of these (probably on my dead PC) but I mostly freehand something as temporary as this.

Hope this is some help,

The past week, my workshop/garage* has reached the 15C level a few times, mostly hovering about 12C. And that's with it's central heating circuit working. Mind you, it drops to -3C outside with the present Arctic weather we've got this end of Europe, similar to Denmark's weather, warmer than Berlin. :)
*Used to be a carport/garage, got converted to a summer apartment then to a workshop.
