Generally if you can't smell it it should THEORETICALLY be fine. However, I've had nothing but let-downs with the junk for clear coats. I'm not sure if people really can use it effectively, or if they just have lower standards than I've come to have...I used to swear by the stuff...but I've had nothing but problems trying to oil weather over it the past couple of years...that's after a week or more of curing...for some reason it clouds badly.
I've moved on to other products. It's possible the formulation change ruined things...like I say I used to love it.
