I have 3 small holes from the gas pedal that the last owner drilled through the fiberglass bottom. I want to fill those holes. Does not have to be perfect I just don;t want it to leak. What is the best way to do this without much time and money.... I would like to take the bolts out and fill the hole with something that would prevent it from leaking. Is there anything like that besides silicone? Thanks
PS I have never worked with fiberglass before so please understand that. Thanks
