Scraping rhino liner off

[JoeKan]

I'm almost ready to make a buy on a sweet looking burb but the main problem I see is that one of the PO's had sprayed rhino liner on the top roof and the bottom half of the front fenders and the passenger door. He did this to keep/stop it from rusting. The present PO has been scraping it off and I must say, it doesn't look bad from where he had scraped.
I'm thinking of sand blasting it if I get the burb. Then I's spray it so it doesn't rust until I can get it all painted.
Do you think sand blasting would take it off or would I be better off scraping and grinding it off to the bear metal?
Thanks for any suggestions,
Joe
