I'll have to ask my friend, the nutrionist
But you're right.
BTW: Do you know a source for the Ral 7034, besides ebay?
Do you plan on adding some red primer over spray on the inside?
These are all custom made. Just ask him if he happen to sell you a spare. If not, buy an etire set and you'll have a lifetime's worth of replacements (for you and maybe others)
It also works with nail polish remover or ABS glue (I recommend the latter)
Get a file (not sandpaper) and make some ABS dust. It dissolves a lot quicker than larger pieces
