I am looking for a source for the original style metalflake used in the older snowmobiles and boats. Actually a 69 Scorpion in this case.

It needs to be square (new stuff is hexagon or diamond shaped) about 1/32 inch in size, and silver.

Any suggestions would be appreciated.

did you check auto body supply shops yet? how about house of kolor?

Check glastronclassics they may help you out !
