My brother is in the process of getting a Defender bulkhead ready for galvanising. He has have had it shot blasted, but it has not removed the seam sealer which he has been told makes a mess of the galvanising.

Can anyone tell me the best way to remove this sealer

Cheers

Steve

You aren't going to like this :- hot air gun, sharp chisel & wipe with cellulose thinners. At least that's how I've done it before - if anyone else know better ... ?

Sharp wood chisel, kevlar gloves, blood, sweat and tears...

Or Central Blast Cleaning, anyone else with an acid dip.

You could try silicon sealant remover to soften it up a bit

Use a wire brush drill bit to get the worst off, then set light to it!

Thanks for that guys, i'll pass info onto him.

Hot gun will make any kind of scraping a lot easier

Oxy torch...burn it and it goes crispy then scrapes off quite easily

Cold does a decent job, go down to your local welding supply, get a cooler full of dry ice and rub it over the sealer until it's good and frozen (you'll need good gloves), then whack it with a mallet and scrape the crumbs away.
