Hi
calling the Fairing experts out there.
I think I run the risk for falling into Fairing Groundhog Day.
At what point do we say that’s enough. I’m only about 40% of the way through fairing but I think I could always find areas to keep going back to and fill and rub down. As much fun as this is.......I’m looking forward to moving onto the next stage but conscious it needs to be right if I want a smooth hull to keep up with Don & Dan.
Just how perfect do the surfaces need to be? I have no idea if imperfections will be taken up by the epoxy top layer and primer etc.
Advice appreciated.
Peter

How long in a piece of string?? but the finished paint job will only be as good at the final fairing? and application of primer which is usually very thick and fills the surface imperfections but not the lumps and bumps....so as long as you are seeing straight lines and no lumps and bumps...when you apply the first coat of Primer it should look very slick....so keep getting rid of lumps and bumps and sort the surface finish with primer...Good luck

Hi Peter,
May I jump on your thread and ask can anyone recommend any good Youtube videos on glassing, coating, fairing and finishing?
I'm not at that stage yet but wondering what is best practice ?
Jim

Hi Jim
Jump in anytime! More the merrier!
I struggled to find a one stop shop. I watched a few of the Sekta builders. Also the West System vids are good - but they don’t tend to be “real life” examples, but good for general techniques.
Boatworks Today I think is good as has very practical approaches.
Also watched The Art of Boat making.
I had to glean bits and pieces from various places. In addition the Gougeon Brothers book and the West System Manual.
Not sure this helps!
Peter

Hi Jim
Thanks for this. Yes that’s the process I am enjoying at the moment. The article writer got a great finish, very encouraging.
If I was to start again I would probably try to put a little less compound on, less thickness/depth, and smooth off with a longer straight edge. I didn’t have one so we just finishing off with the largest plastic squeegee I had, this in itself leaves humps and bumps. So it’s just a matter of iterating through.
I think I would also try to make sure my fibreglass layers overlapped further apart to minimise the build up of glass thickness as much as possible. I little difficult is some areas such as the transom joints, but it may have reduced some of the thickness of fairing I needed.
Nothing wrong with what I have done, just maybe created a little more work for myself!
Just a word of caution to everyone too. I think I have picked up a little sensitivity to the epoxy, as I have done so much of it. I would recommend reviewing your PPE before starting the glassing and fairing. Nothing serious but worth avoiding. In addition to being fully covered, we have used good industrial disposable boiler suits, I would also consider using a good barrier cream on your forearms. It’s really easy to get epoxy on your wrists and forearms when reaching out and you may not notice.
I’m sure others know more about this than me.
But learning.....and smiling still!
