Primer Drying

Just wondering if there was any consensus on primer drying time?

Also in a seperate question could anyone do a tutorial on how to mask and spray the chassis, having problems with this as many of the models have very complex and color intensive bottoms. Thanks and you guys are all an inspiration picking up modeling again after 7 years without.


Current project Tamiya GTR V-spec

lots of tape and patience. that's my method.

oh, and using an airbrush so you can control the amount of paint being applied.

Welcome to AF!

For primer drying time, it all depends on the primer you're using and what you're spraying over it.

As for chassis painting, there aren't much in the way of tricks. Tamiya tape is defiantely the weapon of choice- it's excellent. Combine it with a sharp knife and patience.

Sprayed Tamiya Primer and plannig on using Tamiya spray either Gun Metal or Metallic Red then clear coat.

For chassis masking, you can't beat good old Blu-Tac! (I don't know what it's called in other countries, it's the sticky stuff used for putting up posters.) Here is a picture of my Cayman with some Blu-Tac masking the engine:

I wouldn't use anything else, it's so easy.

Yeah, blutack can be usefull. I also sometimes use wet tissue or aluminum foil to mask large areas instead of taping everything.

For Tamiya paint and primer, they're chemically similar enough that in theory you can start spraying color coats as soon as you've finished inspecting the final application of primer- say half an hour or so. Personally, even when I'm spraying 'compatable' mediums, I like to leave the primer to outgas at least overnight. It takes some discipline not to start spraying body color immediately- especially when the weather's perfect for painting. But time and patience truely are as crucial in body painting as paint and primer. Knowing I'm not going to start paint until tomorrow gives me the time to make sure the primer really is perfect. Primer, paint, decals, clearcoat- as a rule, I never apply more than one of these to a body per day.

I give primer at least over night to dry. I use only Sanyo Gunze Mr. Surfacer or Duplicolor for my bodies, will use Plastikote for anything else in general.

I'll even give it a few hours in the dehydrator if I'm going to be sanding it before doing another coat.
