Ditto with SJ34 on the short life of 'Brightsides'
2 part catalyzed paints have a high learning curve if you want a 'good' job. You have to be careful and observant to changes of ambient temperature, usually have to finish well before the end of the day - to avoid the cooling temps and rising dewpoints that cause water droplets to condense on the work .... and cause 'the dulls', etc. etc. etc.
Perfection is a very good 2 part paint; but, like I state again it does take some expertise (and Don Casey's glass plate method is 'spot on').
Shading the area to be worked, having the boat aligned with the sun - so that one side is not 'hotter' than the other side, etc. etc. etc. etc.
If this is your 'first' 2-part job, I suggest you first practice on a small dinghy hull, and 'experiment' with the goal of a "perfection" job. Hint: 90% of the work is in the "prep".
On the other hand, gelcoat restoration is a much better course and will help hold (or increase) the value of a boat with respect to one that's been 'painted'. Lots of good gel restoration discussions on the net. If interested do websearch: "gelcoat + restoration" boats, etc.
