Just wondering what you guys do when you have a 90 degree flange and almost no gap.
Heres an example:



The gap there is almost nil, but gelcoat will still get in there even if its a tenth of a mm.

When I use filleting wax, even the slightest pressure pushes the flange and this happens:



The other issue is that by using filleting wax, i create a radius, losing some definition.

What do you guys do in these situations? |Could I not just skip the filleting wax and hope the release wax seal a gap that small? Thanks
