Dave, that slight leak may just need crimping. I've used 'Mole Grips' to 
crimp the tabs tighter before , with success. I have as an experiment 
levered open all the tabs and pulled the rad end off. Underneath is a 
rectangular rubberoid seal that is basically a copy of all the end pipework. 
It just seals down under cramping. Leakages [prior to the real corrosion] 
can be just down to crud under the seal. This reminds me that, as my Quantum 
rad is like hen's teeth, I may save the crucial ends to fit on some other 
model :o)
