RE: repairing a boat
Wierd',
Repairing a boat is sort of like repairing a car after a wreck. The basic idea is to 'plug' the hole, and make it look like there was no damage to start with. The first part is easy to do, making it look like there was no damage to start with is the hard part (lol). If the damage is in a spot where there are no compound curves (mostly flat), gluing in a patch and filling in the low spots and sanding smooth is what you do. If the damage envolves compound curves, it's not so easy, since you have to duplicate the 'curves' (still 'do-able' though, just more work). What you use and how, is sort of a "what are you 'handiest' at using" kinda thing. Always keeping in mind that you don't want a 10 pound patch on a 5 pound boat!
As for retaining the batteries in their holder, as suggested, tape or rubber bands, or find a little bitty guy to ride the boat and hold them in... glue as the last resort!
