my white Clarke 4.0 has stayed nice for a year so far...Softscrub w/bleach cleans it up nicely...sum have even reported that they have been able to whiten yellowed tanks w/ the stuff.
the new Clarke tank replaced a badly yellowed
IMS installed by the PO which i believe he bought used...i did notice sumthin interesting when i removed the petcock from the yellowed IMS, the plastic under the petcock is still white :excuseme:
this leads me to believe much to the discoloration is due to surface staining...also have u noticed fuel available currently is almost colorless compared to years ago :smirk:
white just looks better w/ my color scheme(yes, i'm a poser) so my hope is i can keep the new one look'n gud for a few years :thumbsup:
:cheers:
