Author Topic:   Advice needed on Interthanes ( 2 part ) painting

I have been working on the interior/exterior of my 67 Nauset with the goal of repainting the boat myself with Interlux Interthane ( 2 part ). I have received advice / wisdom from this site that seems to indicate that a pretty good job can be obtained rollering and tipping off - this should be fine for the exterior sides, stern and bow where I am dealing with flat surfaces generally. My dilema is regarding the interior, I have spent a ton of time and effort removing an old paint job and patching where crazing and considerably pitting has occured, but now wonder how easy it will be to apply the Interthanes over all the curves etc on the interior, exterior, particularily on the sides where the little ledges are. Can anybody with experience advise on the ease of this operation ? ( Note: I am trying to save $$$$ here by avoiding having the paint sprayed professionally as it is pretty expensive where I live. I realise that I might just have to bite the bullet on this one though.. probably worth it for a good paint job )

Thanks in advance,

Ron

Ron,

Last year I painted my boat with interthane and was not real happy with the end result. Prior to painting, I spent a fair amount of time talking to some locals involved in the boat maintenance business. Most of them told me that you can obtain a professional looking paint job with interthane, but you need to practice and figure out exactly how to use the paint. They also told me that you really need to take your time when painting.

Well to make a long story short, I did not practice enough or take enough time and ended up with a number of runs in the paint. The problem is that you need to get the paint thin enough so that it flows. If it flows right, you will not be able to see brush or roller marks. If the paint gets too thin, it will run when applied to vertical surfaces like the sides of your boat. It takes practice to get the pain properly thinned.

Most of the locals suggested using a high quality brush rather than a roller. That is what I used. Irrespective of what you use, you need to apply the paint in thin coats.

Interthane needs to be applied over a properly primed surface. In addition, make sure you thoroughly wash the boat with soap and water in that this will remove any amines that result from epoxy repairs if you did any such work.

As I look back on the project, I wish I had the boat professionally painted. I had a quote from a local boat yard for $500 if I did the prep work. Not including the prep, it cost me approximately $200 to paint it. Two quarts of interthane ($80), a quart of primer ($22), another quart of interthane to repaint the areas I screwed up the first time ($40) and $40 for thinner and supplies. After the entire adventure, I still am not that happy with the paint job.

If you use interthane, make sure you are in a well ventelated area and wear a respirator. The fumes are nasty. I painted the boat in my garage and it made my entire house smell like solvent. My neighbor was so upset by the smell that he threatened to call the EPA on me. I never have been able to patch up my relationship with my neighbor.

Good luck,

Jeff

Jeff: Sounds like your neighbor needs a "whaler moment" of his own!!

Call the 800 number for customer service at interlux. They give good advice. Their website is yachtpaint.com. I completely restored a well used 1970 16-7 both inside and out with the 2-part interthane plus. Five coats. . . Works great. Good luck. JIM

Some good advice as always. I have heard mixed results on the Interthane and of course am partial to the only paint that should be applied to a boat AWL-GRIP. Regardless of my slanted opinion, here is what I would recommend:

95% of a paint job is prepping and painting and thats of course labor $. I would think that you could find a marina / body shop / buddy / someone that can spray and of course you supply them with a prepped and primed ready to spray hull. This will save you a ton of money and you'll get a good paint job. If your in the MPLS area I'd spray it for you.

Good Luck
Tom

Thanks all for the input and advice. I have decided that due to the many hours I have put into the prep of the boat that it would be worthwhile and certainly wise to finish it right and have it professionally sprayed with Awlgrip. I just know that I do not do enough painting to ensure that I could get a good job with the Interthane. Plus the climate is a bit difficult for me in that the boat is outside and getting good painting days is difficult this time of year what with humidity, wind, etc. I would like to have the boat in the water as soon as possible. ( Thanks for the offer to shoo it yourself Tom, however I live in Bermuda so it will be a plane ride for you ! ) A friend of mine sprays for a living so I have asked him what it will cost given that I have prepped it totally. As Clint Eastwood says, "A man's got to know his limitations.."

Thanks everybody, I think that I will be sending pictures in of this job as it has been a bit of an epic for me.

Ciao,

Ron
