Product Details Tech Specs Info & Guides Data Sheets

Interlux Brightside Polyurethane Topside Paint 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 ensures 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.

Using this paint for over 20 years. It's the Best!

By One Sky from LA, CA

Verified Purchase

Used this on our Sailboat every 5 years for the last 20 years to keep her looking Bristol. Great paint, holds up way longer than label says, still looks good and shiny after 5 years. Jamestown Distributors saved our paint job this year with a decent price and excellent service! Thank you!

Bottom Line Yes, I would recommend to a friend

Great product

By Jere from Texas

Went on smooth and looked just as expected. I do recommend going to the interlux website to look at the colors as the shade of the paint closer matched their website. Great product!

I have used this paint for years on boats

By Joe M. from Versailles, Kentucky

Verified Purchase

I re-painted my cedar/canvas canoe. This paint is the best. One of the best things about it is how it levels itself when rolled on. Almost no tipping needed. And it is plenty tough for a trailered boat.

Bottom Line Yes, I would recommend to a friend

Amazing product to reseal RV roof!

By Valerie from Tennessee

Verified Purchase

After doing a lot of research, this product was recommended again and again to reseal RV roofs. We could not find any locally so ordered from Jamestown Distributors. It was an easy process for online ordering and it arrived in a timely manner. We purchased 1 can for our 1998 Safari Trek 2430 (24 ft) motorhome and used Dicor self-leveling caulk prior to using the Brightside. We cleaned the roof several times prior to using the Brightside- 1x scrubbing with diluted Dawn dish soap and another time wiping it down with diluted TSP cleaner. The product went on easily with a paint roller and brush. It dried evenly and we cannot be happier with how our roof looks! We look forward to no more leaks and increased energy efficiency with the nice bright white roof. (We did not use the entire can, had some leftover.)

Get the brush ready to get good results

By Dream CATcher owner from Southport, NC

Verified Purchase

I started with two different types of foam rollers and all I got was dried bubbles, hundreds per square foot but fortunately I only painted about 10 sqft. After a lot of sanding, I used a 4" brush in a diagonal pattern and the outcome was great.

Bottom Line Yes, I would recommend to a friend

I will buy this again.

By Len from Houston Tx

Verified Purchase

I really like this paint. It flows and levels nicely. I really should have used the primer and applied it at the bottom of the temp range. Basically I abused it but it looks great.
