Methods to remove old seam sealer

[JeepScrambler]

On one of my '84 AK CJ8 postals I am nearing the point where I need to start looking ahead to getting the tub ready for bead blasted once the rust is all repaired. Before I have the tub media blasted I need to remove all of the old seam sealer so I can treat the seams for any rust to prevent any rust creeping out down the road after all the work is done and the Jeep is completed. What have y'all done to remove the old seam sealer? On one of my other tubs I had blasted the media didn't take the old seam sealer out so I'm looking for other methods/ideas on how to get it all removed. Besides the time consuming method of just using a flat blade screw driver and scraping the seams, what are some quicker, more efficient alternatives?

I used a curved end pick to remove the seam sealer on my '83. Really didn't take very long. (Looks like the top one in the link.)

I have used the manual method with scrapers and other tools too but one thing I have done is to carefully heat the sealer with a plumbers torch once it gets very warm almost burnt looking on the surface the removal of it is much easier.

Use a heat gun or a hair dryer so you have no open flame. Heat works well on a lot of compounds and sealers. Also use acetone on a rag to rub off residue that won't come off with heat and scraping.
