Interlux Brightside Polyurethane

Interlux Brightside Polyurethane is the most technically advanced one-part polyurethane available. It contains unique additives that make cleaning easier and help reduce stains and abrasion.

Brightside uses Polyflow 4000, a unique polyurethane resin, which yields excellent flow and leveling characteristics as well as incredible abrasion and chemical resistance. Brightside also takes advantage of the latest in ultraviolet technology which insures longer color and gloss retention.

Together these technologies create a one-part polyurethane which gives the look of a two-part polyurethane with the application ease of a one-part enamel.

I painted my San Juan 24 with Brightsides. It was in the summer, and it went on better by thinning it with their recommended thinner. We rolled it with a foam roller, then tipped it vertically with a foam brush (discarding it for a new one each quarter of the boat). We did three coats, sanding with 320 grit in between. As it dried, it pulled out the brush strokes a great deal, although not 100%. This is looking at it close up. 5 months later, people walking the dock still tell me how pretty that paint job is. Also, we did two coats of the recommended primer. Get advice, take your time, and the name of the game is preparation, preparation, preparation. You can get excellent results with this product.

I have quite a bit of experience with paint, both marine and house paints. I am very pleased with Interlux products. I have a wood boat that is in the water year round uncovered.

I used this paint primarily because of the high gloss value, plus it is getting more difficult to find traditional oil base marine enamel in stores.

The paint goes on smooth and produces a very nice finish, just a little thining, roll and tip, and your all set.

2 years ago I used off white and blue. I have a friend that used yellow. I noticed that after 8 months there was a very noticeable color fade with the blue and the yellow; the off white was difficult to tell, but all lost gloss, and the cabin top was worse than the other areas, more sun Im sure.

I used traditional Interlux yacht enamel for all the white on the boat, that held a much nicer gloss over the same time period.

The next year I experimented with the 2 paints, traditional oil based enamel blue and off white, and polyurethane blue and off white. Yes the Polyurethane lost more gloss and a lot more color, under the same conditions with the same prep. I was much happier with the enamel.

I have heard reports from other wood boat owners that it also tends to crack. Maybe because its a harder paint? Maybe better on fiberglass?

My opinion, good paint, but I much prefer traditional oil based enamel, primarily for color rentention. But there are very few colors available, try Epifanes for variety.

I have had the same experience with other brand Polyurethanes, Petit Easypoxy brown, not just Interlux.

I have used the polyurethane inside with great success.

    Comments about Interlux - Brightside Polyurethane:

    I love using Brightside for decks and hulls both. This is my third boat I have painted and have never had an issue with it filling or glossing right. Even after years, it waxes up to a nice shine in the spring every year!! After Sandy I had some dock rash on the side of one of the boats and the Brightside tipped and rolled over the repair great- even with a dark color!! I know where it is, and its hard to see!!
    The ease of use with the one part paint makes it way worth it!! I had an old gallon that was in the unheated garage for years, and after a good shake this spring used it like primer on this deck and it covered greta!!

      I used this paint to touch up previously painted decks, seats and cabin and it blended very easily and you can't tell where I performed the touch-ups.

      This is one of the best paints I have ever used.

            Comments about Interlux - Brightside Polyurethane:

            I'm new at painting fiberglass but this worked out really well considering my inexperience. I am painting over sections of my boat where it was too difficult to color match worn gelcoat. Most of these areas are distinctly separate from the rest of the boat (hatches that are separated from the deck with wood trim or other delineating features). I have one area on the cabin house that needs to be color matched as closely as possible because the nearest border is too far away to justify painting the entire area. This product levels out surprisingly well with the rolling and tipping technique. Other than bugs and tree litter, it looks as if I sprayed it. The only way I can see to do a better job is to enclose the boat in a finishing tent to keep out any falling debris. I bought the Hatteras off-white 1990 thinking it would match my cream colored mid 80's Hunter 25, but the color dried lighter than the color chart. You just can't tell on a monitor what the final color will be. No fault of the manufacturer or JD. I'm ordering the standard Hatteras off-white for the final coat. I'm hoping this will be a better match.

                    Comments about Interlux - Brightside Polyurethane:

                    Seven years ago I used this to paint my 1966 15' Starcraft Jetstar aluminum boat. The boat is not a showpiece by any means, but I wanted something inexpensive and easy to use to refresh the old tired paint. My boat is always trailered and covered when not in use, so I did paint the entire boat with it, including the below waterline parts. The only prep was sanding off any flaking old paint, and wiping the entire boat down with acetone.

                    The paint held up amazingly well, except for the bottom of the boat where trailering and gravel took off some chunks over the years (and I know it's not meant for below the waterline, so I can accept that). There were some scratches as well from dock dings and the like, but overall, it held up really well and still looked good. So this year I towed it home from the cabin to put a new floor and carpet in, and decided I might as well repaint as well.

                    It's as easy to use as ever. I did not thin it, but rolled it on again right from the can with a foam roller, and used a brush for the tighter areas and closer to where the trim was taped off. I was able to repaint the entire boat with one quart (same color, so that helped), and I don't think I'll need to do another coat since the boat was already the same color.

                    If I were working on a more expensive boat, I might look at a higher end paint and a different method of application, but for my use, this paint is perfect. I suspect we'll upgrade to a larger boat in the next seven years, but if we don't, I'd definitely use this paint again when it comes time to repaint it. We get a lot of compliments on our old boat when cruising around the lake, and many people ask if the paint is original!

                        I have used this paint for over 10 years. The white paint I used on a hatch still had most of it's gloss after 8 years. The areas where I had applied the paint in heavy coats failed first. At the 12 year mark, the paint failed (flaked) completely. This is in Maryland. It is important to lay down thin coats. When applied heavily, the paint chips and scratches easily (almost cakelike). Keep the coats thin and the hardness is quite impressive. I need to press fairly hard with a self tapping screw to scratch it. I do NOT have experience with how well the dark colors resist fading.
