I have had to. But as long as it goes in hot enough, it just peels itself away. Quick chisel and wire brush and onto the next.

I'm thinking of getting my B ticket next. But I could only afford the time in my off season, which is in the winter time, as I put anywhere between 50-60 hour work weeks 8-9 months out of the year. At least I'm certified in all positions. Really opens the doors to a lot of contractors. But like I said, not my day job. Unless I get something full time with the same benefits and pension as my current job.
