I just finished my fenders and I made a stand using 2 x 2, a harbor freight furniture dolly and all thread. I had to put some weight on the base to keep it steady and so it would not flip when it had only one fender. I was able to use this for the front and rear fenders by moving the supports. I only had room for one set of fenders at a time and used this for the body work, prime and paint. Easy to make and disposable. I sprayed the fender underside on a standard body stand as picture in the previous post.
