tips for spraying primer

Sounds like you have a plan! :)

Not related to your issue but this thread made me think of an incident and chuckle, so I though i would share!!

A buddy of mine purchased a 34 Ford 3 window street rod kit. After a 1 1/2year effort working on building the car he was ready for paint. His initial plan was to have it done by a local shop that does restoration work but it was going to take to long so he decided to do it himself. He has never painted anything before and never even owned a spray gun.

The fiberglass body was pretty straight an didn't need much work so after several coats of high build primer and block sanding he was ready for color.

Off to the local paint supply house for some Hugger Orange base coat. The paint he got was supposed to be mixed 1:1 with reducer so he got a gallon of each. Now this guy is of the mind set that you only read the instructions if all else fails. The guy at the paint supply store told him what to do so he never looked at the containers or read the spec sheet.

The paint store gave him lacquer thinner instead of the correct reducer (apparently the cans had similar looking labels). He sprayed on two coats of this mixture when he relaized it was attacking the primer and it was lifting. When i stopped by the entire body was a mess. He had to wait a couple of days for it dry so it could be sanded. He had to sand it right down to the gel coat and start over.

The paint supply store made good by giving him all the materials to reprime, block sand, base and clear. If he had read either can he would have known they didn't go together.
