I have an '83 coach and the stripes are way past tired and done on it. We bought the '83 to get into RV'ing as inexpensively as possible with plans to upgrade later. So, it made no sense to me to pay thousands to have the stripes replaced. On the other hand, I didn't want to have the faded/chipped/peeling stipes to look at every day. A while back I read on here a suggestion of spray painting over the existing stripes. Hmm, hard to imagine it could look worse and a can of spray paint was a cheap test.
I taped the edges of the stripes with blue masking tape and bought a couple cans of spray paint. I lightly sanded the stripe with 220 sand paper, wiped it down with acetone and sprayed it with about 5 light coats of paint.
The results are not bad - not as good as a couple thousands dollars would have done, but not bad at all. I am very happy with the way it is going. Once I finish I will put some before and after photo's up on a thread. The main investment in this is time - it took me about 4 hours to tape one side of the coach - I figure about 16 hours of taping before I am done. Paint, tape, sandpaper and acetone will run about $35.
