Barrier Coats
I am stripping my bottom paint this fall - actually I am having a highly
recommended media blaster do the job. The guy recommends a "coal-tar" barrier coat that he sprays on over the DIY "roll-on" systems from Interlux, Petitt, etc... since I really don't know the difference I would appreciate anyone commenting on it. Thanks. -DanO |

It is a black tar like product. It can do a adequate job as a barrier coat,
but it is a bitch to prep the surface when it is time to repaint the bottom. The tar clogs the sandpaper and it takes 10 times as long as it should to prep the bottom. I would not recommend anyone use it, when the epoxy barrier paints are so easy to apply. "Gene Kearns" wrote in message ...

I'm not sure I would characterize the "roll-on" systems as DIY... if that in any way implies that they are less than professional chemicals. -- Grady-White Gulfstream, out of Southport, NC. http://myworkshop.idleplay.net/cavern/ Homepage http://www.southharbourvillageinn.com/directions.asp Where Southport,NC is located. http://www.southharbourvillageinn.linksysnet.com Real Time Pictures at My Marina http://www.thebayguide.com/rec.boats Rec.boats at Lee Yeaton's Bayguide |

I was thinking about VC-Tar, it was a popular barrier coat used by sail
boats because it gave a nice slick finish. Once the bottom had to be repainted it lost it appeal and people decided it was better to use epoxy and then sand it smooth.

That's interesting information. The bottom guy that I am working with offers it as a spray-on barrier coat. I had never heard of it before.-Dano |

Harry,
Well if that's the case, we'll just have to tax the stuff more. Paul "Harry Krause" wrote in message ... snipped The guy recommends a "coal-tar" barrier coat that he sprays on over the DIY "roll-on" systems from Interlux, snipped Sounds like a by-product of cigarette smoking... |
