I have varathane in a spray can and also have it in a quart. There’s no cleanup if I use the can, are the results compromised compared to a regular sprayer?

I sure look forward to seeing what the experts say about this. Coming from personal experience, I would guess the answer is no. Other than cost, I think the only difference, if there is one, might come from what I think is a thinner mix coming from the spray can. This would only mean more coats required for the same result.

What are you spraying? Aerosol is fine for smaller pieces, but trying to cover a larger flat surface with it won’t go well. It’ll be difficult to get it even. That’s pretty much true for any cone shaped spray pattern.

If you have a fan shaped head that fits on the aerosol you’ll have better luck. Maybe Varathane comes with a fan spray head. Some aerosols do these days. Even then, I wouldn’t try to tackle anything larger than a couple of square feet with a can.

Don’t know, I read something about solids once, but don’t know what they meant.

Use the can up on one project and you’ll be fine. If it sits too long, the poly coagulates over the nozzle and it’s difficult to recover.
First coat goes on kinda “orange peel-ey” because of the individual particles coming from the spray can, if I recall. Second or third coat should solve that though, sanding lightly between coats.
Per sqft of coverage it’s too expensive, but convenience is a plus. No loss of quality if I recall.
