I have two questions that may (probably) have been beat to death. I'm sorting 6 gallons of WW's and finding a lot of WW with only a number No other markings so,
1) how do you treat ww's with only a number and no other markings???
Also , finding several pieces of what appears to be some type of rubber stick-on ww. This is NON-SEGMENTED looks like it may have come a roll and the guy's just cut off the length needed so,
2) Is this stuff any good for casting?????
I'm finding very little of the older type lead segmented ww's.
I know the stick on ww need to be done outside away from anything I don't want covered with soot.
Thank you'
JAMES
