Throw a tarp down, tape the edges you don't want paint on off with painter's tape. Go to HD get the skinny little rollers,(hint they look like hotdogs), a pint of paint, and get to painting. If you like I can help you paint the back of the tank. It is really easy. With those skinny rollers & paint pan you won't make a mess. Remember that with the backgrounds salt creep always finds it's way in between the glass and the background.
The vinyl sounds good and so does the paint but looking maybe to spray it on instead of brushing.Already have that roller Awilda but not the paint.Looking for true blue or black.
Be very careful with spray I am still spraying my stand..But I purposely am taking forever because if you get some in the tank it's a wrap....It makes you tank cycle again..I know this because I made this mistake a couple of years ago...Not sure why but it does make your tank cycle again...
