mixing Pettit Trinidad hard bottom paint ?
I have positive experience using Pettit Trinidad Pro hard bottom paint.
While researching my next purchase I see that Pettit now has Trinidad XSR hard bottom paint. Both paints are similar in description, but have different active ingredients. Instead of choosing one, what do you think of mixing them?
---------------------------
Pettit Trinidad XSR

Pettit Trinidad Pro

or, I could alternate coats.
sequence:
1) Blue Pro
2) Blue XSR
3) Black Pro
4) Black XSR

You can mix 'em. The juicy parts are still the same, you'll just dilute the fancy thios and pyrios.
Me, I'd just use the one with most cuprous oxide.

Well in fact, one of these two products has no cuprous oxide at all.
I'd contact Pettit and ask about the advisability of mixing the two.

Re: mixing Pettit Trinidad hard bottom paint ?
Unless you are a paint chemist who knows ALL the ingredients in the paints and how they interact, this is a bad idea.
When you open a can of bottom paint you see a black funky liquid, that looks like every other black funky liquid that people put on the bottom of their boat. You do NOT see the complexity of the chemistry involved.
If Petit tells you it’s OK to mix them, have fun. Otherwise, just leave the paint formulating to the pros. This is expensive stuff, and not something you know enough to home brew.

Re: mixing Pettit Trinidad hard bottom paint ?
stw,
You don't mention where you are located and may help with a paint choice.
While probably not a problem to mix a copper and "copper-free" paint (still contains copper thiocyanate), why?
If you want to see if the copper free paint would work, then don't muddy the experiment by introducing a traditional cuprous oxide containing paint. Many manufacturers do want to switch out from copper paints and are using Econea and/or zinc pyrithione to create more eco friendly paints.
If you are willing to do the experiment of straight eco paint, I would like to see if the copper free paint works in your area.

Oh, but it is so much more fun to ask people who have no professional knowledge on the subject, rather than ask the people who know, understand, and can help! That would be like reading the manual, which is surely a conspiracy to mis-inform It is so uncool to value expertise over the internet

Re: mixing Pettit Trinidad hard bottom paint ?
I have chosen to stick with Trinidad Pro only, beginning with red base coats and covering with black for future gauging of wear and sanding.
Thanks to the majority that collaborate with good intentions.

Not that it matters, but with a paint as durable as Trinidad, an indicator coat is unlikely to ever be exposed. The paint will have lost its effectiveness (and you will likely haul) long before repeated cleanings wear through the top coat. Of course, much depends upon how foul you let the bottom get between cleanings.

Re: mixing Pettit Trinidad hard bottom paint ?
good point regarding the durability of Trinidad Pro and the unlikely scenario of it flaking or wearing off to expose undercoatings.
I have used Trinidad Pro on my 'other' boat for at least eight years. I applied it over Pettit Protect and very happy with the results.
When recoating, instead of simply cleaning and scuffing the previous paint, I sand much of the previous layers off to avoid excessive buildup over time. My only gauge is when the grey Pettit Protect begins to appear.
Instead of risking the barrier coat to over sanding, I am going to use the red as my indicator of unercoat to completely preserve the Pettit Protect barrier coat layer.
