Dual Action Sander, bang for the buck

For your project and because you didnt say if youre a bodyman for a living, Get a Harbor Freight D/A and sanding discs.....being a hobbyist, this doesnt matter going inexpensive. You can get sanding discs from either Harbor Frieght or PPG painters supply if you want premium products. Make sure you have a compressor with at least 5 hp and a 30 gallon tank for use. The more air supply the better. Good luck!! pads are available in either velcro, or sticky discs. what ever you prefer.
I use sticky discs for use on paint removal. works well.
