I'm not quite ready for paint yet, but fore armed and all that... The current hull situation is that the original navy was painted over with a grey primer (not sure what kind) and then the current light blue was applied with a roller. I'm told it was NOT 2-pack. Am I correct in thinking that this effects my choice in paint/primer?

I may be wrong but I don't think the original colour would have been navy. Most were white, light blue red or mustard yellow, pigmented gelcoat for the top area of hull with clear gelcoat for the underwater section, something that was deliberate as it was thought that adding pigment would degrade the quality of the gelcoat and has been attributed to the Achilles' apparent resistance to Osmosis.
I don't think you will have much of an issue if you use one of the boat enamels, however as the current paint is of unknown origin it may be worth stripping back as much as possible and applying a barrier primer coat, I think Primacon will do this but Ron may be able to give more advice on this, as he has sprayed several to a high standard using simple car paint.
A book that I will recommend is "This Old Boat" by Don Casey isbn: 0-07-157993-1
This details most aspects of restoring a boat on a budget from fibreglass work to full refit.

It all depend s on what finish you expect..
Not being orrible , Laskinners is never going to look like Chille
That finish cost £2500 ,,,, when done second time! just the hull.
Goskars paint was base coat and 6 clear laquer. about
£300 and my work.
but her hull was perfect and flatted with 400 grit wet ,,
Chunky was rough v rough. hours of random orbit from 180 to 240
Then International commercial tractor paint brushed . (synthetic)
I ve not heard a good report on toplac.( I will now).
But hulls are the easy areas ,,, working on top sides is much more difficult.
Primocon is for under coating antifoul, (i think) B good stuff ..

Spraying gives the best finish but is expensive. Roller applied paint is cheaper and gives an acceptable finish.

I've used both International and Jotun paints on various boats over the last few years. Jotun is marginally cheaper but International applies easier and seems to last better.
I've used International Toplac on several boats in varying conditions with varying degrees of results. On hulls I used PreKote as the primer and Toplac as top coat.
On decks I've used PreKote as primer and Interdeck on non slip areas. On smooth areas I used Toplac again.
See my photostream for the keel. Mine hasn't rusted since.

Preparation is key to a good finish as are weather conditions. Paint indoors if possible. Ideally paint when temperatures are 14-18C. Warm paint a little before use. Use a good quality high density foam roller (NOT a Woodies yellow pack). I found FatHog brand good and can be obtained from specialist paint shops. Normal rollers dissolve in the boat paint! You still need to change rollers regularly as they soften.You need to apply several coats for a good finish.
I painted Helm's Deep in cooler weather and the finish isn't shiny but I painted a couple of dinghies in warmer weather and got a great shiny finish. Too warm though and the paint gets tacky while you are still rolling and ruins the finish.
After fairing the hull with marine fillers or epoxy, apply a coat of Prekote and any imperfections will be easier to see. Fair again before 2nd coat.

Have a look at Farmer Boy''s photostream to see the finish he achieved earlier this year on Cirrus.

Don't try to remove flies that land on wet paint. You'll just ruin that spot. Wait till it's dried and remove them then and there'll be less of a mark.

Have fun

Sorry yes you are right Ron Primacon is antifoul primer and used as a barrier coat for different antifouls.
I am sure Ron that a lot of us would be happy with the finish you got on Goskar.
If you are not using 2 pack finish for the paint job International Yacht Primer would give an good base, though many don't bother and just rub down the old paint and apply the gloss coat, but as is always the case you get the finish in direct proportion to the preparation time you put in.
I know there was an article in PBO some time ago covering DIY boat painting, I will look it out.
Another thing that might influence your choice of colour is that the darker the paint the more perfect the preparation and application has to be as every imperfection shows up, with darker colours.

Daddsie is the man for painting. His advise, use a tipping brush, thin paint 5-10%, warm paint, warm day. He gets spectacular results with a brush, just check his photo stream for Rumrunner and an Albin Ballard he did. Other point is that they always look so much better on the water than on the hard after you have painted them.
