    So the "customer" says she wants Buddy Guy polka dots John Deere green with John Deere yellow dots on the mustang bass. I imagine they make the 3M fineline tape wide enough to cut my own dots, but it sure would save a ton of time and effort if I could just buy them. Anybody know a source? Or if you've done a buddy guy like finish, what did you use?

    Thanks for looking...

    I would go to a hobby shop or a business/office supply to see if I could find appropriate sized circles. At office supply places, they sell stick on 'tags' in circular format...I don't know if they are big enough, though. They would be handy is they do make them big enough since they already have adhesive on the back side.

    You could always go to a sign shop and have them do a mask for you out of vinyl. This way you can control the exact size and spacing of the dots.

    thanks I thought about the "staples" approach, but will stickers give me the nice tight edge like the fineline tape?

    Another question is how will wet sanding over the transition between the two colors.

    one big mask, that's a good idea!

    That's what Bob the Motorcycle Painter would do.

    I think that is what I would think about doing.

    Let the machines do your work! ;)

    coolbeans, we just happen to have one in town. I shouldn't have a problem with the vinyl wrapping around the sides. I love when we get corroboration from a pro, thanks buck.

    so with a big mask this means that the dots would go on last as opposed to the other way around with stickers. Does anybody know the pros and cons of each method?

    You may try a hair dryer (Not A Heat gun) on low to help you make edge.

    If it were me I would spray the Dot color and wet sand do your vinyl mask
    and spray clear to seal the masking to get a nice tight dot then spray the last
    color. Top coat with loads of clear very thin coats!

    Sorry lost my mind . .
    Spray the guitar the main color
    Spray clear and wet sand I would NOT use nitro!
    have the vinyl shop make the dots in the color of the dots !
    put the dots on the guitar
    and clear !

    Just like a fender logo get it

    Hope this helps.

    I would advise against using the dots as permanent. You will never get a smooth coat that way.
    I would use the dots taken out of the vinyl. I would apply the dot color, let dry, clear coat 2 or 3 coats, let dry and fine sand, put the vinyl dots in place and spray the 'non-dot' color. Pull the vinyl dots before that color coat is completely dry and apply 3 clear coats. Sand smooth with care not to go through the clear to the colors. Finish with 2-3 clear coats, sand and polish. Lot of work this way, but the resrsults would be better, imho.
    Using the vinyl dots would make it easier to apply the vinyl. Pulling the vinyl around the edges will be problematic, I would think. IF you choose to go this route, you might reconsider teh dot material. IF you can find large enough stick on dots at an office supply, I would think the cost would be much less.
    Personally, I would not hesitate to do this in lacquer...nitro or acrylic....but then that is my chosen finish in almost any situation.

    martino: good tip spraying clear between the colors. It seems logical that it would give you a nice clean edge as you're not sanding on a edge that transitions from one color the next.

    Wally: permanent dots would have to be very thin I imagine, you might be able to get away with it sort of like the paisley projects I've seen. Of course those are a single sheet but there is the edge that goes all the way 'round.

    Thanks to both of you for your input

    You definitely do not want to leave the vinyl dots on and clear over them. The vinyl is too thick and you will never get it completely smooth. I would probably spray the dot colour first then use a mask made up of dots and not holes as it will be much easier to manipulate over the edges than with a mask made up of holes. When you have the mask cut out, have the sign shop apply a transfer tape over it (basically really wide masking tape) this way the dots will all come off together and you wont have to worry about applying them individually.

    I hope what I'm thinking came across in my typing.

    I have done this many times it is easy compared to Oh lets say
    putting a smooth coat of clear over flake!

    You do have to start with good vinyl .
    http://www.signsupply.com/Vinyl/FDC/2100.asp
    and you need good tools.

    Ok so a few points.

    RapidTac makes putting on vinyl graphic more like a water slide decal
    smooth no bubbles.

    [​IMG]


    The felt block makes a world of difference for smoothing out the bubbles
    too!

    At this point I would scuff the whole thing down with 000 scotch pad
    and put a very thin coat (dust coat or tac-coat) and start building from
    there.

    Good luck!

    I understand it can be done, and have done it before, but I found it impossible to get the clear perfectly smooth. Of course my experience is with bicycles and not guitars but the same should apply.

    Thanks! this is too cool. I'll stop by the sign shop for sure. I really appreciate the effort put forth.

    Is that a squire 51 test bed?

    You bring up A Good point I do not know if you can get enough clear
    on bike frame or the EDGE of a guitar like the forarm end of a strat.
    So you are right!

    The bike looks sharp by the way!
    does it weigh as much as a tele.

    Now if it is a tele style body with a binding it would simple!
    The vinyl I cut are all less thick than a sheet of paper.
