For the fiberglass guru's out there, at what point do you stop working with fiberglass and start touching up with some sort of bog? (Sorry if my question is fundamentally wrong, but this is an area where I have no experience). If I need to block up a small 10cm long section of a kit (say make it 1cm taller) that is not structural, is there a problem with doing this with bog, or do you have to go back and extend the fiberglass? Any help, even to tell me I have no idea what I'm talking about and need to look at etc. etc. etc.... would be appreciated. Thanks
