: How much filling is really necessary after sanding?

: I've sanded to what I think is smooth and fair but there are still a couple
: of 6" gaps about the thickness of a business card but I'm frightened
: to fill & sand because I think I've sanded those areas more than
: enough & I don't want to risk sanding through!!!!

: What are the implications of glassing and epoxying over such gaps?

Hi,

I would suggest a seal coat at this point when it sets to a "green cure" you could look at these gaps again and if there are still some that could benefit from a fill then there is no proplem to fill at this point. Do your fills and LIGHTLY sand with 220 and do you glass. Just my take, others here may have a suggestion more to your likeing, especially if you are not wanting to do a seal coat (not manditory but a good step in my opinion).
