Not 40 yet but there's a few lying around here

It's looks a little tragic at first ( the shell) but it's pretty damn good actually

Came with the x pack cleaner assembly and a bit of original rs stuff

I remember what you said about the brown one I got from central NSW when I picked the roof up. I’m thinking the same about you on this one. Please it could only get better if you said it’s numbers matching. Love it and well done.

yes- all the numbers match
 
Im thinking of buying a blaster - im a bit time poor so may help to get thru them all

My Sand blaster is my best tool. Make a lance and then all your panels are rust free. I use a dried washed sand from bunnings and it won’t rust afterwards as their is no salt left in it. Saves hours and hours but it’s messy.

I wouldn't be using sand on panels, there is probably a good reason why the pros use garnet, wall nuts etc.  My guess is if too heavy it could generate too much heat and distort panels. 
 
Pretty sure you don't need to etch after blasting as blasting provides the key.  The guys over here diamond bead blast and then apply 2 pac primer.
 
If you use phosphoric acid with your scotch pads it will be faster and be treating at the same time.  Again don't etch an acid treatment.  Pics are before and after of a test section I did on an mg guard years ago, just scotch pad and diluted acid.  Sometimes it goes a bit yellow, sometimes purple.
 

Their is no issue using sand. If you read the text books you should never blast both sides of the same panel as it will distort. None of this really is an issue with a small sand blaster. Also garnet being tougher will make the issue worse not better. I have garnet but I prefer sand and used three or four times it becomes finer and pits less. The pits just make a good key for primer but I would still etch prime regardless.
