Answer: 
Of course it can. Just rough up the surface. I often use paint (oil or latex) and rub it into the surface for a smokey look. Latex must be thoroughly dry. Oil can be covered after 24 hours. Use 150 then 220 grit sandpaper to give it some grip. If you're looking to put on a thick layer of paint then use this product as a clear coat then no, don't do it.

Answer: 
Although I would consider this product suitable for exterior use, even for the above the water-level for boats, I do not think that it would last long in the environment that you are thinking of. Normal expansion and contraction will probably make micro-cracks which would be exacerbated by submersion and acid.
I don't know what would work for you, possibly some sort of thicker PVC or fiberglass Read More

Answer: 
Order of sheens are : Flat, Matte, Eggshell, Satin, Semi-Gloss, (Hi) Gloss. Eggshell is about the lowest sheen that's easily cleaned. With urethanes semi-gloss is the most popular finish while (Hi) Gloss is considered "tacky" (NOT elegant). You can lower the sheen by buffing with 0000 steel wool and oil.

1 qt. Semi-Gloss Helmsman Indoor/Outdoor Spar Urethane is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from Polyurethene products are best purchased in quart sizes The quart size product is actually a differt product than the gallon containers due to government regs on solvent based products there. Is only so much VOC allowed per contianer like 350 per container. so the gallon actually has more water than solvent that is why the quart products are a better product.

Rated 5 out of 5 by from Good stuff This makes an excellent durable finish on gunstocks when hand rubbed. I also handrub it for furniture refinishing. Wear gloves.....it is tough to get it off of your hands. I use the thin plastic disposables made for food handling.

Rated 5 out of 5 by from GREAT STUFF I have used this for over 10 years. It is fantastic indoor or outdoor. I have also used this on Oak for marine applications and could not believe how long it lasted.

Rated 1 out of 5 by from Look for something else! I've used this stuff for years. I understand that it has been reformulated, and the result is pathetic. It is impossible to apply without bubbles forming everywhere, causing more sanding and additional coats. This makes it (even) more expensive and time consuming. I've had better luck with the newer water-based products, and they are much easier clean-up. This isn't the same spar varnish from a decade ago. Look for another product!
