I was planning on bead blasting, do I need to use primer before the wrinkle paint?



No primer required with VHT wrinkle paint. Just prepare the surface by bead blasting (insure all rust is removed) and a wipe down of lacquer thiner to remove any dust or oil before spraying.
Instructions from a can of VHT that was in the shop include
Do not spray at temperatures below 70 degrees
For best results spray a heavy coat followed by 2 or 3
additional thiner coats 2 minutes apart.
Size of the wrinkle will depend on the thickness of the
paint.
Hold the can 8 to 10 inches from the work.
Curing of paint to wrinkle finish will take 20 minutes to
12 hours after final application.
This process may be accerated by a heat lamp or hair dryer.
