I've had so such luck with the CASA ones ... I think one page says I have about 3 cpl's...
It was getting out of hand .. way to fix .. remove licence from porn mag style plastic sleeve ... arm yourself with a cotton bud dipped in turps or metho ... hold your breathe and begin to rub inside .. the old licence / medical ink comes off quite easily and leaves a nice aroma from CASA when they inspect your licence the next time ...
Dont forget to get your pretty picture before the $200 fee!.
