Look at label on can if urethane is oil based it should be fine. Think of it like basic chemistry. Oil and water dont mix, xlene based products are used to strip oil, so if ur using a xlene base over oil thats a no brainer. The urethane I use is a xlene base so I wld never use over oil. Im just not sure if they sell a oilbased urethane so check the labels
Yes. Make sure tha if you are using a latex spar you only use it over latex. If it is oil based you can use it over whichever. HOWEVER BE ADVISED even if it says non-yellowing, I have yet to find a spar varnish that does not yellow over time. This can be frustrating over pale colours, particularly white
Yes, you can.
Assuming you're talking about wood finishing, spar urethane can be used over a water sealer. In fact, the combination is better than just a sealant or just the spar urethane. A very durable finish for outdoor wood products is soaking the unfinished wood with boiled linseed oil, letting the linseed oil cure, removing excess cured linseed oil, then applying spar urethane.
Why would you?
It's a very good marine quality varnish.
Yes, I just did it last week. If it's for outdoors, make sure to put 2 to 3 coats of poly on it. I recommend Minwax Helsman Spar Urethane.
Yes, you can.
Yes, you can.
Lacquer can cause the paint to bubble or crack due to the very hot solvent that is a part of lacquer. If you want a clear coat over paint, a better choice is spar varnish over oil base paint and arcylic urethane over latex.

Read the directions printed on the can.
Only if it is a car with exposed wood. Called a Woody. If you are painting metal the results will be unsatisfactory.

You can use spar, however I do not recommend it. In my experience spar tends to yellow over time and that would alter the artwork. Also, if you are planning on using the bow as anything other than a decoration hanging on a wall, I'd check with a good bowyer to be certain the top coating you intend to use won't crack, check or in some way limit the usefulness of your bow.
1-During the case, the judge directed lawyers not to spar with each other in court. 2-It is natural for boys to spar with their friends over girls they like. 3-The rough weather broke the sailing boat's spar and it had to be rescued by the lifeboat.
No. The spar varnish acts as the sealer. Apply a thin coat and allow it to dry. Apply a second coat and allow it to dry. These two coats should have sealed the pores of the wood. Apply the third coat slightly thicker, so you get a nice even "wet look" to the wood.
