Bart,
I had a lot of "pinstripes" from this trip too, but I guess most of them where just in the dust on top of the paint. I'm guessing that yours are actually IN the paint?
I've had a lot of luck with Zaino's products and before the last ZuZoo I spent 19 hours on the exterior of the VX, alone, and she ended up looking like an oil slick. No swirl marks, no pinstripes...nothing. Just SMOOOOOOTH clean paint.
Here's the process:
1. Wash the VX with dish soap. This will get rid of any left over wax.
2. Clay bar all of the paint. http://www.zainostore.com/Merchant2/...oduct_Count=20
3. Wash again to remove the residue from the claybar, but this time use Zaino's car wash; no heavy chemicals. http://www.zainostore.com/Merchant2/...oduct_Count=14
4. Apply anit-swirl treatment. http://www.zainostore.com/Merchant2/...oduct_Count=21
5. 1st wax coat with polish for swirl marks http://www.zainostore.com/Merchant2/...roduct_Count=8 with Zaino's cure accelerator added. http://www.zainostore.com/Merchant2/...oduct_Count=11
6. Apply two coats of gloss enhancer. http://www.zainostore.com/Merchant2/...oduct_Count=13
7. 2nd coat of wax for clear coats. http://www.zainostore.com/Merchant2/...roduct_Count=6
8. Finish up with spray seal. http://www.zainostore.com/Merchant2/...oduct_Count=12

After all of that the results where AMAZING. It's super time consuming, and a little expensive, but it may buy you another year or two before having to get the VX repainted.
