Ready to paint the bottom

[RogerBoat]

After hours and hours of research and sanding the bottom of this 35 yr. old fiberglass hull, I am ready to order materials, I am going to do a barrier coat, probably SeaHawk "TuffStuff" and coat with Supermarine SM 1000...not antifoulant, but advertises long life and easy on water friction.

An issue to address which I haven't seen discussed anywhere is...the boat is setting on three pylons. So I must apply the materials to the rest of the boat, let it cure... then put it back on the trailer so I can get at where the pylons were at. This means I must merge the different materials to be applied, new paint to cured material.

I guess I will tape these areas off a few inches into the new coating, feather the edge, then sand, fill and coat the three areas where the pylons were. Any advice about this process?

Also, any comments about the products mentioned above would be apreciated.

Thanks

Is this the same boat as your 40 yr old ? http://forums.iboats.com/showthread.php?t=529545&p=3604517#post3604517

Thin the Tuff stuff.. or get ready to put on some melted marshmellows. Shake it..do not stirr it or power mix it.

YD.

Yes that's the same boat. That's disturbing. Marshmellows? I take it Tuff stuff isn't your favorite. I also looked at Interlux 2000E. If I recall correctly, the literature for the tuff stuff, had more favorable literature relative to pot time, and less coats to achieved correct thickness.

But then experience is everything and thats why I started this thread. If you have a preference, I would be glad to consider it.

I've never used tuff Stuff, But I have used Supermarine SM1000.

It's nice stuff- BUT FOLLOW THE DIRECTIONS EXACTLY. Especially when it comes to proper thinners, wet film thickness, and curing times. Do not try to apply it too thickly, and give it plenty of time to dry before attempting to recoat it. I've been really happy with it on my boat, and plan to use their products again!

You will never get the mil thickness from TS in 3 coats. Yes IP2000 is better IMHO. The pot time is just fine.
So no matter which you choose you will be doing 4-5 coats of either product ( IP2000 smells BAD though... nasty nasty bad ! ).

YD.
