if you are taking off sheets of delaminated glass you might want to spend a little more time on it and do a true epoxy bottom job using West system or totalboat. 2000e is a 5 year barrier coat, West system a 10. it's a lot harder to sand but it's a lot better protection.
that said, you might consider adding in some new glass with delamination that bad.
on my Catalina 30 the hull is 1/4" in most places and up to 1/2" around the keel grid, if I lost 3/16 of an inch like that is would concern me more than just a light barrier coat.
that said you can save some money using totalboat if they ship where you live, there's often 30% coupons online.
I mean the glass all seems great, and I’m actually removing two 3mm thick coats of some kind fo epoxy barrier and a few coats of anti fouling above it. Does this look right? Should I keep removing all these layers?
So far it comes off in sheets very easily 💀 haha. I’ll stop sanding to the glass 2/3 of the way up the keel after the cracking stops, or is that premature?
I hate to say it but I would start over at bare glass below the waterline. I’ve done it before and it was worth the pain the one time versus chasing the problem forever.
Doing it the right way would involve 3-4 base layers followed by 2 or 3 top layers. Read the manuals of the products you use. You're looking at 1-2 weeks of work ahead, not full time days but you need drying in between layers
Correct me if I’m wrong but the interlux 2000e specifies a dry time of 4 hours between each coat, and then depending on the bottom paint between 4-8 hours between coat and no more than 16 hours out of the water after applying the final coat.
That sounds like two days of work, and so however long the refinishing takes plus that.
Marina folks call it the 'thumbprint test': press your thumbnail or a coin and see if it indents. If it does, it will still chemically bond. If it's too hard, it needs to be cleaned and sanded.
It could be done in a week if you have the time to do it every day for 5ish days but there is no real shortcut. There may be some products i am not aware of but the right way takes time
Dang I appreciate the advice. I’m the same way. I only have until Friday morning though but I will see what I can do to push the deadline back and just do the whole thing
I recommend Peel Away marine paint stripper. You brush it on and cover with some sheets they sell that are like parchment paper. You come back the next day and everything is falling off. Scraping is way easier, faster and safer than all that sanding. Then you have to neutralize the acidity on the hull (detailed in the instructions). You may have a tiny bit of sanding still, but very little in my experience. Good luck!
There are lots that are cheaper, but there aren't any that are better. If you cheap out on this then you are due for another expensive repaint much sooner. It is worth it to spend the money now and do it correctly.

Barrier coat under that would be a good start. You have a lot of chipping and sanding ahead.

Thank you for the advice, I’m looking at using interprotect 2000e unless you know of a cheaper/superior alternative.

That's the right barrier. Getting down to the glass everywhere is the real project.

Interprotect has very specific guidelines for recoating to ensure adhesion between layers.

This is amazing advice, I will try this out! It’s already peeling in a lot of spots anyways, thank you so much!

It's when you paint the bottom, with paint.

What’s paint?
drroop@reddit
Paint is toxic chemicals you spread over the bottoms of boats and your hands and clothes.
You put it on the bottom of boats like every year or so, and every few years you sand it off again so you can get it in your lungs too.
Sometimes people put it on walls and canvas too for no good reason.

Paint · Paint is a material or mixture that, when applied to a solid material and allowed to dry, adds a protective film-like layer.

Thanks for the input but I’m not sure what you mean by that?

He/she is making akibe at the previous owner for not painting the hull... Unless you're choosing not to also!
