I just finished up my off-season projects:
ripped out the sprinkler valve system and replaced with Tsunami fill pumps
vented the ballast bags
window tint (20%)
re-located the batteries for more room in storage
complete scrubbing of vinyl with exquisite cleaner, followed with babe's seat saver for UV protection
last to-do is to orbital buff with Driven's Restore to remove surface scratches, then follow up with Driven's Marine Polish
Of course, I've already been out a few times this year, so my season has already started (perk of livin in AZ
)
