Post subject:  How many kilos of media to blast a mini?

I need to strip a thin layer of etch primer off a bare mini shell (inside out and under side), doors , bonnet and boot. I have access to a blasting set up and I want to use glass media.

Has anyone blasted a mini here? How many kilos of media did you use?

I have two options for buying the glass media,
- Buy a 1 Ton bag of crushed recycled glass
- Buy 25 Kilo bags of media

The recycled glass is the most economical option but if it is far too much I don't want to be stuck with it, also it comes in one big bag making it hard to shift.

Will you been able to try and reuse the media? Using tarps on the floor to catch, and then sieving the media can save a lot of waste.

Some primers come off with thinners and a quick wipe of a rag, have you tried that?

I used a small sandblaster to blast most of the corners/seams/crevices of Susanna and I went through about four buckets of Garnet, but I was reusing what I could catch.
I much preferred using paint stripper on any flat panel sections, then a quick scuff with 180 grit paper before priming

Thanks for your reply Andrew. I have thought about using solvent or paint stripper. I might give that a go first. I have some surface rust to deal with too so that's why I was looking at blasting.

Hi all I'm new here.Just starting on my first mini I bought as a rolling shell. I bought 500 kg of glass bead to clean up the whole thing.i sealed up an area of the garage to do it,and away we go, I used about 300 kg but was a bit wasteful (lazy) to clean up properly, and reckon I probably threw away about 100kg or more.

Thanks for your reply, if the paint stripper doesn't work out I'll give the blasting a go.

Single pack etch should just wipe off with a bit of general purpose paint thinners
