For those who have done it, curious as to the time and effort required to sandblast firebox and hood sides. Is it easy enough for a first-timer? I have refurbed two grills. The second was better than the first. Hoping third, which will also be a bit of a re-do/combining parts with the first - turning two 1000LXs into one , will be better than the second. There are DIY sandblasts booths nearby, so just looking for some input on what's involved, and expected results. Thanks.
