Re: $$$$$Painting the boat
This is also dependent on what kind of paint you are using.
Awlgrip, Alexseal, Interlux (perfection or brightsides?), Imron.
All the 2 part poly's are expensive and fairly close in price, awlgrip is the most pricey. But I've never seen as hard of a fully cured surface as awlgrip provides.
Also, the amount of prep work necessary will add $$$. Stress cracks everywhere will take awhile to grind, fill and sand.
