To prime or not to prime...

[twilight]

I've been working with Floquil paints lately and I've noticed when I prime parts to be painted and after the primer dries apply paint (with a brush)the primer pulls up and blends with the paint causing streaks.:curse: Am I doing something wrong? I'm just thinking of painting the parts without the primer. What do you guys do? Will this happen with an airbrush?


Thanks,
Mark

Give the primer 48 hours to dry, I wait until I can't smell the paint myself, usually 3-4 days.

I will go with Bob on the 48 hrs if your brushing, 24 if using a airbush.

Are you thoroughly washing your parts with detergent and water and allowing them to dry before priming? Just another thought. Parting agents used in the forming process will keep paint from adhering.

Jim, I just used a piece of the spur to check if the primer was going to run. I usually do wash my model pieces and will be sure to do it this time, too. And thanks for the 48 hr suggestions, I'll give that a try! Thanks Guys!:thumb:

Mark: are you using Floquil for the primer as well? Floquil's thinner (dio-sol) used to be a mild solvent which attacked platics. I think it may have been reformulated. Floquil was suitable for application to metal without primer, unless you needed it for colour.

David, I am using Floquil's primer and I am using on plastic. I'm about to experiment with the 48 hr suggestion offered by the previous posts.

Thanks:thumb:

At the last protype meet, earlier this year, I found the best solvent to clean parts is a laundry product called "Shout" and rinsing your parts in water after cleaning. Worst cleaning product is dishwashing liquids. Dishwashing liquids all contain emolients added to keep your hands soft. The emolients cannot be rinsed off your parts.
