Does it look something like this??
- This is the 1969 we had.
You can actually see some scratches that have gone through the clear coat but not damage the aluminum.
This shows where the clear coat has failed over the years and the aluminum has oxidized.
This trailer will need to be stripped and polished.
You can do various levels of polish - if you want the "clad/clearcoat" look which is not a bad look either - then you could probably do that yourself and then take her in for a new clear coat somewhere - or if you have the skill, tools and location - you could do that yourself too.
