I always found stuffing a load of rolled up newspaper into the crack very effective in such situations however it must be stated not every lady will enjoy the experience.
For a more durable repair I suggest Chockfast (red) mixed with fibreglass resin and liberal application of sheep sh1t and watergrass is quite efficacious.
