Rbob You have confirmed my suspicions.  I thought a out the rub rail idea.  I’m not sure I could pull it off.   I still need to consider what happens at the end of the rub rail.  I also need to figure out where to break the paint around the transom and splashwell too. 
   The good news is I have 3 more months on the longboard to figure it out. 
Did you use a DA or RO sander at all for your paint project?

[Rbob]

Todd,

Most of sanding down to #220 was done by hand with blocks of different sizes and shapes.  After blocking just apply the dry "guide coat" and use a Random Orbital sander (D/A) with a interface pad and #320 - #400 and for corners and edges I put the sandpaper on a piece of scotchbrite. Interface pad is awesome for final sanding.

3 years  ago today I made the first sawdust for my boat.  It’s been a long road and a mostly enjoyable trip. 

[Todd j]

Ready for another round!

[Rbob]

Your boat is going to look great and I promise your memory of sanding will fade!

How many coats of high build primer will you apply for the final round?  I remember you have finish primer and hopefully that is a non-sanding type.

At any rate you are closer than ever and it's a new year.

[Todd j]

Rbob, because I wasn’t looking ahead I have 2 single coats of high build sanded between applications.  This time I will apply 2 coats on the fairbody and lower ph side panels, sheer, anchor deck and splashwell.   I will use whatever is left where it’s easy to sand if I use it at all. 
   I do plan to hit my finish primer with 320 as directed.  No more blocking by hand.  I bought those kick ass pads you suggested.  Looking forward to trying them out

[Todd j]

The interface pads that Rbob recommended work great.  I sanded 1 side of the hull very quickly and very easily.   I have yet to decide how I want to deal with the inside and outside corners.

[Rbob]

Todd,

"I have yet to decide how I want to deal with the inside and outside corners."

What I did on inside corners was wrap a piece of scotchbrite around a plastic tube / dowel etc and attached velcro sandpaper to the scotchbrite.  Outside corners is a matter of finesse, long 45 degree passes with a block as you roll over the outside corner, you can finish the outside corner by hand with a piece of scotchbrite with velcro sandpaper attached.

I will try to take a pic tomorrow of the setup that works pretty good.

[Todd j]

Sounds good.  I’m working up enough steam to get off the couch and go sand some more

[Rbob]

Todd,

Here are some examples below, try to find a tube in size that is similar to what you are sanding, use guide coat of course and sandpaper grit from #180 (first pass) up to #320 or what ever you decide.

The scotchbrite I use comes in a roll so you can use any length you want but 8-12" is plenty, or just cut up the scotch brite to attach to the length of sandpaper you are using.

Wow, nice tip rbob... Inside corners are the bane of my existance... outside ones too but not quite as much

[Todd j]

Groovy!!  Thanks for the pics

[Todd j]

Better than sanding
