Hiding skin eruption, wrapping it with this item (9)

Ross

I believe the answer is:

thrashing

I'm a little stuck... Click here to teach me more about this clue!

'hiding skin' is the definition.
'thrashing' can be an answer for 'hiding' (I've seen this before). I'm not certain of the 'skin' bit.

'eruption wrapping it with this item' is the wordplay.
I cannot quite see how this works, but
'eruption' could be 'rash' (synonyms) and 'rash' is found in the answer.
'it' could be 'thing' and 'thing' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for thrashing that I've seen before include "A very heady defeat" , "punishment" , "Hiding" , "beating" .)
