Good stuff, easy to apply.
Great product! Goes on smooth and easy, and I love that it only needs one coat. I used it on my RV roof, and it sealed everything up perfectly—no more leaks. The bright white finish also reflects heat nicely, which helps keep the inside cooler. Definitely feels durable and built to last. Included a picture. Roof was treated a week earlier so some dirt and leaves are on roof. Hardest part is the prep before applying.

MARLIN COATINGS is an awesome product
This coating is amazing. Does exactly what is says it will do. Very thick, like melted cheese, self leveling, applies easily. Just clean the roof very well, tape your seams, brush on around the air units and vents and roll on the rest of the roof with a medium knap micro fiber roller. I did my 35 ft motorhome for under $600 including 3 rolls of seam tape. Much cheaper and better than replacing a whole roof with membrane. What's better is that it's totally waterproof. A must for all rv's.

High-quality, roof coating.
Saved my home, couldn't afford to pay someone to coat or replace my flat vinyl roof. Found this stuff and purchased 25 gallons to apply myself. Cleaned surface real well, applied with a roller on a mild day. Put it on think, it self levels almost to a smooth shine. Been a year no problems.

Initial quality is good!
I chip brush applied this coating (in direct sunlight) to my metal patio cover where it attaches/contacts my home. Weather at the time of application was 98F and 25% humidity. The coating is thick and goes on like pancake syrup; it has a high gloss finish and rubber like feel when it cures. Don't leave the bucket fully uncovered for more than a few minutes, especially in direct sunlight. It does have a self leveling feature and the initial quality is good. I had an unexpected light rain fall on it six hours after I applied it and it held up well, with no running. The next day it rained and I didn't have any leaks. Time will tell about the longevity of it's leak protection.

Research PAYS! What a score!
I love this company! This material is PERFECT! Way less then Hen or Dic less than Rubber S, folks these guys are making a great product FOR LESS! Even the container was the best! I still have a nice seal on my remainder! I nailed it with this US company out of Florida, covers so well, self leveling property is like MAGIC I have never experienced self leveling like this, drys fast (don't panic) use >thin foam roller! My 1st roller was your normal paint soft roller, this was difficult! The key to a great job = short pole, 'thin' foam roller, cheap throw away bin brush for your prep around vents is perfectly fine, 1st night do all ac, fan,skylightes, ext.. next day roll, I did 1 thin coat second day, then final on 3rd day. Do it right THIS IS HOW! The soft paint roller as I say was trouble 1/2 or 3/4 IS A MISTAKE! So I simply went over the entire roof with some elbow came back next morning with my thin foam roller, short 4' pole & man ! Oh babay, did I say the self leveling was FREAKING AMAZING? ..Sure,sure I did.

This stuff is absolutely awesome!
So far it's working awesome! Super slippery so nothing is going to stay on the roof like it used to. Snow slid right off this past winter! I did the pre wash primer step, let it dry, and applied it. Used a 3/8 nap roller and tray and I did a 2'x2' area with a dip and I still only used half a pail. I plan on doing another coat in spring. Keeps heat in camper down a ton being white too so thats a plus Just don't try walking on it if it's wet or you'll be on the ground before you realize what's going on. Bottom line, it's pricey but worth every penny!
