Great for wood as it fills and covers very well.

Used to prime the hull of a wood-canvas canoe after filling the canvas. Excellent leveling/smoothing after 2 coats, sands well without clogging when fully cured.

I'm not sure just what is upsetting the complainers here, as this is the best primer I have ever used. Excellent coverage and hiding, fills open grain, dries relatively quickly, sands beautifully. It's also great for outdoor trim applications, and clearly superior to most of the stuff that is sold in the paint stores as primer. Some of those products are too thin and runny, while others are a total bear to sand. I use this for everything, and it has never let me down.

I liked the simplicity of a one part undercoat. I used it on the boat interior, which already had two coats epoxy. I had a question about using it on epoxied wood the Interlux tech rep was very helpful. Then I painted two coats Wet Edge Cold Cure. I am vary happy with the end result

I have years of experience in the marine industry. I started working in a boat yard 20 years ago and since then have worked on clients, friends, family, and my personal boats. I also have 15 years of commercial blue water experience sailing onboard ships in positions from Ordinary Seaman all the way to Unlimited Master. I have used many Interlux products along with many other manufactures products both in the recreational and commercial marine industries. Out of all the primers I have ever used this is the WORST primer. I tried thick, thin, roll and tip, etc. and no matter how the primer was applied or no matter how long it was allowed to dry I always ended up with horrible results. Ultimately the only way I was able to properly sand this product for top coating with Interlux Brightside was by wet sanding. I have three different Festool sanders along with the respective dust collector and Festool abrasives, none of them were able to sand this primer for anything longer than a few seconds before loading up. I was eventually able to get mediocre results by hand wet sanding with 220 grit wet/dry abrasive. I will NEVER use this product again. I will start trying different 1 part polys and their respective primer even though Brightside has been my go to topcoat for a easy and durable 1 part poly.

I used Pre-Kote on my deck of a fiberglass boat. It goes on very easy and has excellent coverage. It was just the product I was hoping for.

Good product. Price is right, easy to apply and dries quickly enough that runs don't occur. Also easy to sand to a smooth finish and it fills a lot of the small divots that occur in your previous epoxy layers

Two or three coats of Pre Coat sanded well gives a great base for a fabulous Brightside finish. Thin the Brightside with a capful of 333 thinner to enhance flow in warmer weather.
