I agree with BAZ. "better to spend alittle time to find and fix the problem then all your jobs will be better looking"
"I'm going into damage control mode, I'm going to try the speckled black. Probably can't see the small imprevections then."
If you gotta get this job done and you can do that perhaps you'll be ok, but it's the chicken SSTT way out maybe. If you take that approach for all your work though you will never be a PRO. When you have a problem you must track it down and kill it! Fix it now, if you don't then it will haunt you for ever.
Happy Halloween
