I have started removing the undercoating on my car, and so far I only have the front fenders cleared.
On one fender, I used a scraper, on the other I used a wire cup brush on an angle grinder. Is there a preferred way to remove this stuff? I did search on this, but did not find any threads that said the best way to do it. I don't have media blaster, and don't fancy the mess involved with that. If there is an easier way then scraping and grinding, I'd love to hear it. Zach |

I haven't used it but Eastwood sells something you spray on undercoating to soften it.

the wirebrush on an angle grinder or drill works best
it's a tedious job though and takes some elbow grease you don't want to soften the undercoating if it's soft, chances are you will smear it all over the place instead of brushing it off media blasting won't take it of either because the undercoating is soft/flexible media blasting only works on hard/solid surfaces, like paint, bondo, etc... |

I used a heat gun and scraper and it pretty much peeled off in sheets.

Depends on the undercoating and the area it's in. But generally speaking...
Try scraping first. A lot of undercoating is dried out and flakes off easily (relatively speaking) in fenderwells especially. Heat gun and a scraper to get the bulk of it off if it's soft. 4" heavy wire cup brush on an angle grinder for the rest. The remaining residue will come off with brake cleaner. It's work, but it's easily do-able. |
