Re: My tri-hull transom replacement w/ pics
Another milestone got passed today! I finally got some primer on all that fairing work. And yet, more sanding will no doubt follow.
I finished up some final sanding that needed to be done and wiped down everything to prep for the primer coat. I used acetone at first and finished the clean-up with MEKP. Thankfully, nothing blew up. It was 20 degrees outside and I did some venting with a window fan.
I laid down a perimeter of plain old painter's tape to keep from making a mess to get a line around the primered area.
I used a razor to get a clean line around the hull stiffeners.
Here is what I used to apply the primer. A plain old foam roller and a china bristle brush to get the corners and tip the primer off.
After taping the perimeter and doing some additional cleaning up I mixed up the components of the primer. Be sure if you use this stuff that you buy some 2333n thinner to cut the primer. The primer must be thinned before use.
This primer starts out in two parts. The base is very thick and comes out of the can like mashmallow cream. (i love that stuff) The hardener (reactor) is like honey. After the 2333n is added the mix comes up like thick paint.
The best way to treat this stuff is like a coating rather than a paint. BY that I mean if you leave a thin spot it will give you a headache when you sand it this stuff. I used the brush to work outward from the corners. And a foam roller to blend in the middle sections.
Blending is the trick. Work with fresh batches and don?t wait too long to get the primer applied. If you wait the full induction time on the can, it is likely the primer will get thick at the end of a pan. So start a little early getting the primer rolled on.
Here is where I ended up at bed time. All of the faired areas are covered with primer. I think I did a good job getting it all as level as possible. We shall see how the sanding goes. At very least a second coat will be needed. And I plan to get some "glazing compound" for some obvious pinholes and low spots I saw.
I am glad I did all this, but man is this allot of sanding! I look forward to the finish coat. If you ever paid allot of money to a guy to do this kind of work on one of your boats, believe me, there is a reason. Sand..sand ..sand.
I complain but the truth is I am enjoying it. I would rather be painting, but this will do for now. Keeps me out of trouble.
