looks heavily undersealed, and been there a while too. dont scrape it off, use a pin hammer and start at one end and work to the other. nice ring sound is what your after, the deeper the thud the grottier it is, until its replaced by the crisp packet sound as the hammer dissapears into it. like you dont know that tho, from the bulkhead.....
keep stripping till the bulkhead comes off, then we'll know what we're playing with.
if the shocks aint leaking, should pass mot. how solid/spongy are they?
personally, i'd keep em'.
