Review: Easier to get a perfect finish than other spray urethanes - I have used tons of this stuff over the years for restorations. In my opinion, the Minwax Helmsman clear gloss spray spar urethane is the best finish freely available in the southeast United States. I have used many different common finishes over twenty-plus years. The difference that I like so much is that the spray is very thin. Getting a perfect, smooth, even surface is easier with the nozzle and formulation with this product. It is not perfect. The coverage is poor, the color is tinted, and the dry-time is long. Also, it can't be used on top of water-based paints. Every finish has its use. I just come back to this one the most.
Review: Quality Product - Quality Results - Excellent quality and durability for an outdoor Spar Urethane. I have used this on many items including signs, steps and a snow sled. Goes on smooth and sands nicely between coats

## Questions & Answers

**Q: Can this product be applied to painted surfaces.**
A: I have used it over wood carvings painted with acrylic paints and have have excellent results in an outdoor evironment.

**Q: can i apply the oil based urethane over a water based paint to protect it?**
A: You can but this is why you should use a water based poly over the oil poly Oil based poly has an amber hue, whereas water based poly is clear. An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor. ... Water based poly dries much faster, and several coats (up to 4) can be applied in one day. This explains why fritz the cat who did answer this question as well is why theirs yellowed

**Q: How is the viscocity out of the can, is it more like warm syrup or more like water...or somewhere in between? Thank you!**
A: Maybe Slightly Thinner than warm Syrup, So probably between Warm Syrup & Water. A word of advice though, I had an extremely difficult time working with this product & had to sand and reapply many coats to get a satisfactory finish. It dries fast & if you run a brush over it after is has sat more than a minute it will create rough brush marks. Additionally if you apply more than a very thin layer it will crack similar to a crackle pattern. Unless you are putting this over a pure white background I would recommend that you use the standard "Crystal Clear" non-water based urethane. It has only a light yellow tint and is much easier to work with in my experience.

**Q: Can this product be applied over an exterior wood stain?**
A: In fact it can, but being unfamiliar with the product, I purchase it thinking that it's use would result in a shine. I learned that "spar" must mean something other than gloss or high gloss. I then purchased the "Minwax Gloss aerosol which gave me the desired result, although several coats were required.

### ⭐⭐⭐⭐⭐ My favorite varnish to use indoor or outdoors
*by A***N on June 12, 2024*

I live this product . I use for refinishing everything and protecting my hammock wood which is outside year round . Used on very fine furniture in thin coats it has lasted and performed for thirty years without needed any care at all . I can also carelessly slab it onto my expensive hammock wood divider which I have had for 24 years now and it’s still in great shape . I have it on dressers and cherry end tables from 1930’s and an 1800’s rocker as well as all Cesar chests and milking benches from early 1800’s . I use the spray can it foam brush from the van for all old baskets to keep them pristine too. This way all is protected from moisture and water . I have put thin coats of it on 1800’s ice cream parlor chairs as well as cane seating with no ill effects . It makes cleaning and dusting so much easier . Also I no longer have to use coasters for drinks nor worry about light scratching of the wood . I love antique furniture . I love to seal in the character of the furniture with light hand sanding and seven thin coats of urethane on them is perfection . With this I have character and can also sponge off my furniture without worrying about dampening and lifting old varnish . Works incredibly well with a beautiful long lasting shine it brings out the patina and grains of the woods and straw. It’s easy to use and quite forgiving as well as easily sanded . The coverage is perfect . It is thick enough to apply without being runny or fussy . It adheres beautifully and no problems with fine bubbles . Adds depth and warmth and covers stain while adhering very well to both bare wood and stained wood . I have been using this product for eons on so many things . I have tried some others products over the years but this has been the best and easiest to use . I could not believe how well it liked in the caned seating . And the light coatings have not cracked nor peeled in years . I also used it for my papasan chairs . Twenty four years later they are still pristine !
