Fiberglass work?

When laying new glass over old do you have to grind all the gelcoat away before laying the new glass? Do the seams in each layer have to overlap or is it sufficient to overlap the but joints with the following layers? Is the job stronger or weaker if you lay up all the layers at one time or let each layer set before wetting the next?
