Rob,

I've had great success with 2k clear over apron decals.

To be honest I suspect the bunnings 1k stuff may react.  Generally there is extra decal - the same material just outside of the decal.  If that makes sense.

Maybe trim a bit of the spare stuff off and spend $6.00 on a can and give it a whirl.

think I'll give that a try thank Marty and see what happens. Gotta admit this classic arcade decal is pretty ordinary in respect to keeping things authentic. The colours and font seem quite off. I would expect better from a licenced product. I did a water decal that was much better but couldn't do an A3 print and the decal material seemed thicker than what I expected. Hence trying this now. If this works ok, my next move is doing the scan and getting an embryon decal made locally. At least the fonts will be true and hopefully the colours
