Without pictures its a bit hard to understand the size of each defect and the scope of the issue as in is it 20 or in my case 10,000
The big issue is having it come out again with use as boats are always flexing and expanding and contracting with the weather
I used system3 epoxy filler as most of the stuff the PO had done was popping out again

If a dirty bottom slows you down what do you think it does to your boat To view links or images in signatures your post count must be 10 or greater. You currently have 0 posts.
The usual fix for gelcoat cracks is to "vee" out the crack with something like a Dremel tool and then fill with new gelcoat. If its not pure while, you will need to tint it.

The article says to use hardener if you are in a hurry. If you have time to let the epoxy cure on it's own, according to the article, you don't need to use it. I have a few spots on my boat to do the same thing to once it gets warmed up.

One is a 'fast' hardener intended to be used at lower temperatures.. at normal temperatures it would kick too fast. The 105 is the resin, the 205 or 206 are the different catalysts. You cannot use the resin without a catalyst.
For jobs like this it's important to use the thickeners described to avoid sag.. it also eases sanding and fairing later on.
Looks like the OP's catamaran had some serious voids in the initial construction and they are all coming to roost now... best of luck, it will be a time consuming job - with the finishing part the hardest.

BTW - there are so many 'white' gel coats, depending on manufacturer, and even if you have a wet match it may not cure the same shade. That is where the seasoned expert comes in.
