Painting the Varnish WHICH PAINT??

I'm about to embark on getting the outside varnish painted on my new to me MT 34 DC. Sherwin Williams offers several paints in the color I want. They are : Industrial Enamel HS alkyd. SeaGuard 1000 Marine Alkyd Enamel .Pro Industrial Waterbased Alkyd Urethane Enamel . Anyone here ever used these paints ? Color to be "Saucy Gold" Or "Marigold ."

OK, I guess I don't quite understand what you are doing.

Are you planning on painting over the existing varnish, or stripping it back to the wood and applying a primer and then the paint?

I’m not familiar with any of those paints but I would avoid the water based one. Water based paints have not been very successful as marine paints. I would also avoid two part paints as the strong solvents used will likely lift the varnish.

My choice would be Interlux Briteside.

For choice would you paint over varnish?

Until recently no I wouldnít. There was a recent thread talking about this and someone suggested that if you wanted to revert to varnish in the future, a coat of varnish would keep the paint out of the wood grain. This would save you a lot of sanding when you wanted to go back to varnish. Iíve never tried it.

We painted our rails in self priming water based Sherman Williams housepaint.
Sanded flaking varnish off to bare wood with 60 grit on a sander and rolled in two coats.

2 years down the track , zero cover and in a semi tropical climate it looks as good as the day it went on.
All above deck timber currently getting the same treatment.

Bird doo lifts Brightside unless it is removed quickly- Brightside also losses most of its gloss in 2 years.

Yes, but you took all the varnish off and painted the wood from bare.

Here we are thinking about painting over the varnish.

It has fresh Vietnam varnish- which will not hold up in Florida- I'm using that as a primer and just sanding to rough up. In places where the wood is bare and was not Vietnamesed varnished-I'm sanding smooth-then primer -then 2 coats of one of the paints I listed.

Do you have a lot of wood, would it be prohibitive to take it all back to the base and redo?

I would sand the old varnish lightly and use an oil based primer , then any single part oil paint.

This will make stripping easier as primer is softer than enamel and allow the scraping to have a warning strip at the top of the varnish.

The masking would not need to be removed between the primer coat and the covering paint.

So its not much extra work.

Not quite sure what birds and sun exist near your boat.....

Pelicans?

But brightside in my world and quite a few others seem to do fine against both.

Mine doesnt care about bird crap, even if left till a rainstorm ....and it does dull a tad, not being a 2 part.... so its no mirror but has enough shine to look as good as the rest of the boat. But it will bubble if something wet is left on it for weeks on end.

Unless you are doing a total makeover with a 2 part and removing most external features.....most will agree that brightside is good enough compared to the expense and labor of the alternative.

And for me, not having a climate controlled shed, I am not going to waste my time worrying about the perfect job as it wouldnt happen anyhow or on a reasonable time table.

The types of paint you are discussing are good paints, similar what we use on the assistance towboats. They dull way more and faster than brightside (we have used both, even at the same time on different parts of the boat). But we repaint the hulls every year as they get abused and the white uppers, a little dull but clean looks goid from the end of a tow line...

The best expert job I have seen on painted teak is OC Divers boat, who epoxied and filled first..... his rails look like painted glass over steel.

I did this. Painted all my exterior bright work. Sand then apply 6-7 coats of Pettit EZ Poxy. I unscrewed all my bright work, it made it easier. It’s been 1 1/2 years and still looks good.

Weíve been using one part Brightsides for 10 plus years on our exterior pilot house doors, eye brow and name boards. The name boards have been stripped down and the lettering replaced once since weíve owned Hobo (11 years). We get 3-7 years before I have to touch up but being a one part, itís easier and it blends in well. We also use their primer.

There are no perfect paints.

I have been seriously considering painting over some of the varnished wood. Love its look but the load is finally getting to me. My side window frames have a lot of detail causing hours of prep and varnishing.

Yes, I will overpaint the varnish so if I, or the next owners, ever decide to go back it will be possible.

I contacted Interlux and they told me:
--- not to use a two part paint as the solvents will lift the varnish no matter how well it is primed.
---the Brightside paint will do a good job.



As far as I'm concerned if it goes to a 5-7 year repainting interval that would be a huge relief. As it is now the varnish need sanding and recoating every year.

Briteside or Pettit Ez Poxy will start to lose gloss at about the two year mark in South Florida. The further north you are, the longer it will last. I’m happy with it out to about three years. At that point I think it needs a light sanding and another coat.

If you are in South Florida and only get two years before you feel the need to recoating the Briteside, you will have avoided recoating the varnish at least three times.

We refer to this as Awlgrip for teak.

Poor inside florescent lighting. It's Carinthia Blue.

Everyone who has seen it, really likes it. Boot stripes are the same color.

I fully expect your timetable is right for your area. I've seen Brightside in other uses where I like and it's not unreasonable to expect a 5 year cycle.
For me that would be a huge bonus.

Last year I just missed 200 hr and I did not get everything, close but not quite.

Darn boat expect to be used. Well, my wife and I expected to use it.
