GREAT job on the restoration!!!
It seems we have the same affliction for the classic Cigs. Thanks for keeping it old school.
Here's some pics of my '79 Cig 33 Limited Edition. I completed the interior (cockpit & cabin) just this past summer.
I've found that Watco Teak Oil works great for the older teak areas. Works good for us up here in the more northern climates anyway. I know that Florida sun wrecks havoc on it though.
Post some more pics of the 28. Would love to see more.
