First, check with whomever did the work. Most paint shops have recommendations...or they should. I had some minor work done and they told me to wait 90 days.
I generally recommend to my clients that they wait 3-4 months before using a wax/sealant after a spray. Different manufactures recommend different intervals, but most all of them cure within 4 months. If you do regular washes, the paint will be just fine waiting that long.
i just had some new paint on my whole truck and they said to me 8 weeks will give it time to cure before waxing and not to use harsh cleaning chems.. hope this helps
