I have a B25 I plan on painting this winter.  It is dry sailed and in need of paint, top and bottom.  I intend on spraying and do not have the equipment for a two part paint so i plan on using Interlux brightsides. 

 

What is best for speed?  should I paint and then apply McLube polish?  Should I not apply anything but wetsand with 1000?

The advantage of dry sailing is less annual maintenance on the bottom and no paint buildup. 

The disadvantage, other than cost, is keeping the bottom clean and fast between races.

I sail out of Naptown on a bigger boat with a Durepox bottom (zero antifouling properties).  After a 3 day summer regatta, the bottom gets a little slimy/fuzzy.  

Get something you can clean.

Also, the bay will stain most light colors brownish.  The owner uses an acid solution to clean/whiten up the bottom after each race.  

No free lunch, but it is less work than burnishing baltoplate every year

Pettit easypoxy flows out better and lasts longer than bright side. Neither work underwater. Use Vivid below waterline. Bright colors and burnishable. Wetsands easy for slick bottom.

Thanks all.  I only want to do this once.

 

None of you said to go with McLube polish over the paint.  Interesting.

If you use brightside you will be doing this more than once. You could use performance epoxy, durepox or awl grip. Then polish with mclube or wax a few times a year if you really want to dork out.

Then use a product that is made specifically for dry sailing and not some in-water-storage bottom paint.  Durepox or VC performance epoxy are both great for this application

If you only want to do this once, I wouldn't use a 1 part enamel like Brighsides or Easypoxy......Especially if you ramp launch.

If you're going to spray, why can't you use a 2part epoxy like Awlgrip 545?
100 x harder than an enamel and is formulated to be wet sanded....unlike a 1 part topcoat.

Interlux used to have a dry sail paint called vc eco. No antifoul, hard finish and was said to stand up to abrasion due to trailer/cradles. Perfect for a melges or a j/70. Not sure if it's still produced, or what's replaced it if not.

What spray equipment that will shoot Brightside not shoot a two-component paint?

Two part epoxies require a positive flow air feed as the fumes are toxic when spraying.  A one part epoxy does not or I would buy Awlgrip.  Spraying a two part epoxy with a $50 mask can kill you.
