... How's the dagger board coming along?
As I expected... my fiber-glassing looks like a couple of monkey did it... while mating.
I've got to grind parts of it off and patch it and I'm concerned about the patched areas being weak.
At the moment, its rainy and below 50. Tomorrow 43 is the high with more rain. And as we've already clued in the northerners... we just don't work outside in the cold.
Plus, I've self imposed not working on my later projects till the first ones are done and its frustrating me to death not having a heated workshop like I used to have before I retired.
A good thing I've got plenty of cheese to go with my whine.

Russ, my wife has been incredibly good natured about it. But, I believe that I have used up my error-credits. I am going to have to do my research very thoroughly before I replace the head!
I will sand, wash, and use some solvent to degrease and dewax. Then start over.
I'm glad Russ mentioned that. Mold release will prevent new finish from sticking... Seems like your plan is coming together.
Forgot to mention that. I use acetone for that and my 3D printing projects. Also the smell reminds me of my grand mother and mom taking off nail polish every day of their lives until someone decided it was carcinogenic. They certainly didn't die of it. I can't even imagine how long the poor lab rats had to swim in the stuff to cause cancer. Wonder how similar that cancer looks to drowning.

Another reason my avatar is appropriate .
First, I doubt it's that bad. But, if it is, I'm sure you'll get it squared away. Second, it didn't sound like whining to me. And third, that is one terrifying avatar.

Well, as of writing this, the entire interior has been scraped and sanded! And we are still speaking to each other. 80 - 100 grit worked well; it has also ensured that none of our finger recognition devices will accept our finger prints...
Christmas Day will be the wash, wipe with acetone, and sand any missed spots. I've got the https://www.westmarine.com/buy/interlux ... 21_003_016 primer from Westmarine ($$$ ) and I'll be experimenting with that during the week before it goes onto the entire interior.

Glad you and the Admiral are still speaking! I think experimenting is a great plan!
I'm sure you read the reviews on the link you posted, but if not, make sure you stir the paint very well - including scraping the bottom. The reviews indicated failure to thoroughly mix would keep the coating from drying properly.
Good luck and keep us posted!

Wait until you get to use the acetone .... It melts Nitrile gloves too
Consider a coat of Interlux Interprotect 2000E as a primer. It's a barrier coat but also an excellent primer on many substrates. It permanently bonds to the exterior hull gellcoat, so I suspect it would also adhere to the inner liner, especially one that has been pre-sanded like yours.
Some of the problems with using non-marine paint are the flexing of the hull, high humidity, temperature variations, and smooth fiberglass substrate. In theory, the 2000E addresses all of these, but note that I HAVEN'T tried 2000E on the inner liner, so this isn't experienced advice. It is only where I personally would start if I had the same challenge.
I took the battery cover home to use as my test piece. After scraping, sanding, washing, acetone wipe, and dry I painted it with the INTERLUX–Brightside Pre-Kote Primer as indicated above. As per instruction, I gave it a good stir before starting. The primer bonded beautifully. I have now painted two additional coats of glossy latex and these appear good too. I will give them a few days and then check bond and ability to wash and clean before commencing on the rest of the boat.
I finished painting last night as the sun set! I will provide a full set of details (and photos - when I have removed the tape) but wanted to jot down a few bullet points before I forget:
Prep:
Due to my snafu with the wrong primer, I spent a long 3 days scraping off paint.
This was followed by a thorough sanding of the entire interior surface with 100 grit.
I washed the surface (sanding creates literal mounds of dust - wear a mask) with water and then followed that with an acetone wash.
Painting:
I primed the surface with Interlux Pre-Kote (1 coat = ~1/2 - 3/4 of a gallon).
I painted the storage spaces and cabin floor with Valspar porch paint (2 to 3 coats = ~1/2 a gallon).
I painted the interior with Valspar high gloss latex (that I tested on the battery cover a month ago) in an off-white (2 coats = 1 gallon).
At the end of the day (I had two very long days doing the two coats) I think it looked ok; not professional finish but good enough for what I want. I will follow up with pictures and keep a log on wear and tear.
My final thoughts would be that if I knew the effort and final finish, I would have found a boat with a white interior or learned to live with the tan.
