Epoxy Paints
Posted Monday, January 10, 2011 12:15 PM

 Does anyone have a source for automotive quality Epoxy paints? The hardware stores have nothing but Garage floor paints. I'm interested in using the Creed method to brush the paint on, let it setup then sand and polish to perfection. I'm looking for epoxy paint for Fiberglass hulls. I also don't want to be restricted to Boat bottom colors.

Brush on automotive paint? Appliance epoxy is readily available in spray cans. What I don't like about it is it goes on somewhat heavy. Krylon plastic paint works pretty well. I like Dupli-color Truck paint from the auto stores. Goes on thin and comes in lots of colors.

 Appliance epoxy comes in 2 colors White or Almond. Not great graphic getters.

2 stage epoxies allow an almost gel coat finish. the Brush technique  is used by David Creed who makes the Widget IOM kits. He brushes it on  the fiberglass, it is self leveling and a great way to seal casting imperfections and pinholes. 2 coats applied then wet sanding to a glossy luster. Much better choice with automotive paints

Sounds great Tom. I am sure with all the hand work it would be a beautiful finish. I would love to check it out. Don't forget IOMs have to add weight to be class legal. US1Ms sailors would shed their skin like a snake to save weight.

 I used enamels on My IOM but the problem is that the patches keep pulling it up paint, the boom vang scrapes away a little and I get a chip everytime Ernie t bones me. The Idea of using the epoxy is to use it to fill and finish the pinholes with something as strong as the hull.

My Us1m is carbon fiber but it got still had to be painted to plug pinhole leaks.

The other reality is that the paints either in a spray can or a bucket available in California are terrible because of EPA requirements that the state has posted. Thats why you have to repaint your house every 3 years because the paint chalks and lifts right off the surface of wood and trim.

 Go to a Marine store like West Marine. They sell Hull paints in both two part and one part. Interlux makes a one part epoxy called Brightsides which comes in many colors in quart sizes for around $30. They also sell four colors:Black, white, dark Blue and Red in pint size for $15. They have two thinners one for Brushing only and one for Spraying, get the correct one!

 I know house paints are all latex or acrylic now so don’t hold up well in the weather. Modern enamels are very subject to chipping and pealing on wood or soft substrates and you need excellent surface preparation for enamel to stick and should use a primer. What works better now (on houses) is the paint originally formulated for concrete block called “solid body stain”. It will stay on wood in the weather much better and without primer. You can add booster to it to help it stay clean as it is flat paint.

There are water base spay cans but you can still get good oil based enamels and lacquers in rattle cans unless they changed it first of the year and didn’t tell me. You can also buy old school oil base enamel in quarts at paint stores. Used for sign painting and things like that. You have to let it cure for a while but if applied well makes a hard surface that is hell to sand off. I have used old school enamel on wooden boats, centerboards and rudders with good results but is seems too heavy for scale models to me.   

The two part 100% solid (no solvents) will be the most durable, less porous and better for the environment. Wasn’t always that way, early two part epoxies were toxic and smelled bad.  

Another thing about spraying paint is it kind of bounces a little on impact and does a double kiss over holes so is not a good way to fill pin holes. That’s probably why they recommend brushing on as it works it into the holes better.
