Love this scrapper.

works pretty good especially with the door open...
far enough away that you don't feel the heat...
really pulverizes any speedbumps.

I use a big screw driver I bought at Harbor Freight, works great. If I still was working up in the shop ( had torches there) I'd heat it up and put a slight bend in it but it's fine as is too.

I use a paint scraper....works great!

yeah.. there are 100 things u can use...
I bought this because of the lenght and being able to scrape in an open flame without knuckle burn.
with being able to hold it with 2 hands, it gives the pressure to blast a carbon speedbump in 1 shot.
