buffing interlux brightside?

So, no matter how many times I sand and reapply a properly 333'd coat of brightside, I still get some "dull" areas, and "tip borders" in my finish. 

Is there a tip or technique that I can use after my paint has cured to buff up those dull spots and "erase" the minor foam brush marks? 

Thanks!

 

 

John,

Interlux doesn't recommend buffing Brightside. That being said, after waiting two weeks for it to thououghly cure, I used an automotive buffer and polishing compound on the exterior of my Peeler Skiff. Then we buffed it with Turtle Wax. Ended up looking like gel-coat and still looks great after 5 seasons on the saltwarer. My grandson re-waxes it once a year.

Cheers,

Dick
