Paint Prep for wood

Anyone ever tried this? I'm looking to paint an outdoor garage, and am too lazy to scrap the old paint by hand.

gonna need some good goggles and a mask, those work but if you are doing much it will throw a ton of debris.

if it is thick old paint try a flap wheel for a 4" grinder, much faster but you have to watch how much pressure you apply. still gonna throw dust but more manageable than a drill.

Much faster sounds much better to me. I don't have an angle grinder, but maybe Wallmart has an el cheapo. Thanks.

You'd be better off with a pressure washer, much faster. What doesn't come off, just paint over it.

I am impatiently waiting on my machine to arrive that will take the paint off of anything I point it at. One day, maybe before the end of summer, I will have it.
