Re: Metal Flake
Had to jump in here and recommend against this...
While anything is possible, this isn't the way to get the look you are after and as has already been said, it ain't gonna look right...
Even if you practice on a piece of whatever, if it isn't the same size as the boat, and you do it exactly the same way, in exactly the same conditions [ I recommend a professional automotive type spray booth]...everytime...it won't look right...
Unless you are an ACE with a spray gun, have tons of practice doing this type of painting, and all the conditions are perfect...you are going to waste a lot of time, energy, material and money...
However, all that being said, it's your wallet, your time and your boat...you can do whatever you want...and in the end you might get lucky and make me eat my words...[I usually put some garlic on them, just in case...

Best of Luck,
