holes all over her body

[baz-r]

i got holes there multiplying and im lousing control (to grease theme tune)
seriously no joking i got problems with me grp gel cracking off to find voids to the matting underneath its realy getting me down
most popped up after i had to remove most of the body and put out in the garden under the heat of the sun had made the trapped air bubbles expand.
also have some other minor refinishing to do

now i need to know the best way to repair it. i know i will need some gel in black (dont know code) and light blue (bs18E50) what else will i need and how do i go about fixing it? also where can i buy small amounts of gel from i need to do the job

i also have some DA sander marks in places of the black polished finish and a few odd marks i think the best way to fix this would to flat it of with a block ,some soapy water and very fine wet and dry then polish it back with somthing.
what is the best option to polish the dull matt finish out after do i use normal auto paint products or somthing else?
