I bought some self adhesive clear vinyl and stuck a square shape over the entire circle. i then carefully with a scalpel, cut round to give me a perfect circle (although its not perfectly round) the shape i needed. i also masked off the already red sections.
Dont let the red spray dry, otherwise it goes matt finish. i left the first coat for a few mins then just sprayed another on top.
i also left the french fry bit non masked so i could spray it, as i have left my french fries off as i never really liked them. looks far cleaner & simpler without them i think.
You need to let the spray dry totally. i think i left mine most of the day then sprayed the laquer on top - probably about 3 coats in total.
Remember, if it goes wrong you can always remove the spray and start again. i would defo take time masking everything off to make sure that the end result is perfect. i would also recommend the clear vinyl for the indicator shape rather than masking tape, as it gives a real crisp edge, i got mine from a place called 'hobby craft'. the final result shoudl give a perfect OEM look. oh, and remember to spray them equally as one of mine first time round looked a little lighter than the other.
Good luck!
