bottm paint

[ehall686]

 The paint on the bottom of my cp 19 is popping off, you can get your finger nail behind and a little piece will come right off.  So this year I decided to sand down the bottom paint.  Now my question is do I need to put on some kind of primer behind VC-17 when it is down to the gel coat after it is sanded?

Before sanding:

If your dead set on vc 17 i would suggest you use 2000 first.
dont let anyone talk you into vc tar......
I am a boat tech specializing in interlux and repair work.
Just curious.......why vc17.......it really is a expensive paint and hard to get away from if you change paint styles......

The 2000 is a good idea with any bottom paint but especially so with vc17 as you have a surface to sand down too besides gelcoat. Sometimes gelcoat holds the bottom paint in the little crevaces and its hard to get it all out then.

So why vc 17? Not saying it is bad just harder to deal with.....

My dad bought some a few years ago and I have 2 cans unopened so I don't have to buy any to get the job done. But I thought that it may need some kind of primer.

How do you paint under the stand supports (the carpeted things)?

Id definetly do 2000 job then. For that youll need 2 gallons. I only know that since i bought enough to do mine.
you right for the vc17 and since you have the 2 quarts id definetly use em.......free is awesome too

As far as those pads guys on here do it several ways. Some arent for the light hearted. My suggestion is you tie the boat down on one side to the trailer. On the tied down side that bunk will remain up so literally you are pulling the boat down against the bunk on one side. The other side you can drop the supports and then paint.
The boat wont fall on you since it is tied on other side and the bunk is keeping it from falling onto that side.

After the one side is done then put the bunk back in place with a car jack and tighten back down. Move the lines that you tied down other side to trailer to the side you have finished and take other side down repeating the process.

I plan to hoist mine so i havent done what i said here but that is what i would do if i didnt have the money to pay for the hoist or access to the equipment.

Bottom of keel.......well.......thats another story. Frankly i like safety so much i would pay to have it hoisted. Just how i am. Guys on here have had good ideas on how to do that. But i am one of those faint hearted guys and i like to be alive. LOL

hope that helps.

WoW 2 gallons, I was told that it would take 1/2 gallon of bottom paint to do the whole job, why is the 2000 stuff not going that far?

I noticed on the transom that it is painted up about 2" In your humble opinion would you leave that strip on or match the rest of the Transom.

I went to the boat store and picked up the 2000 the directions recamends 4 to 5 coats on the bottom so that would take up that 2 gallons.  I hope to have some left over for a few coats on a foiled rudder that I'm building.

Ill have to look at my transom and see what that looks like back there.
I dont remember paint on mine. And i havent done mine yet.


If you coat any metal with vc 17 make sure you have that 2000 between it.
If you dont the vc will interact with the metal and create corrosion between them.

Ill post on here later today with how high it is painted on mine

Rule of thumb is to have the lines of the boat flow and i do remember that the old bottom job line looked good

When the 19 is sitting on her lines in still water, the transom should not be contact with the water.  Instead, about 3/4" gap--perhaps slightly more, should be present. Therefore no transom paint is required.  Just clean it up with FSR or a magic eraser once in a while to remove stains.
