No fisheye reducer for me
! Been there. Beside what's been mentioned about it, each time you mix more paint it has to be exactly the same mix as the previous. If not....you really have problems. If you read the label it will tell you that the surface has to be absolutely clean (I haven't used it in years). That being the case you won't have problems with the fisheye reducer. But, if it's ABSOLUTELY clean, you don't need it
. My paint store sells it but won't push or recommend it.
