If you are using Tamiya sprays it is better to move the ball in the can in a circular motion to stir the paint than to shake it in all directions. Their paint has allot of pressure in the can and those bubbles are caused by the propellant in the can. Shaking the paint up seems to cause the paint to foam up in the can.here is a link concerning the use of their paints.

and always warm the can first. Put it for a few minutes in a bath of warm water. Then shake, then spray.

That is my spraying ritual now.

Whenever I feel lazy and not warm it first the paint job is not good.

I second that, those little tamiya paint cans are superb if you prepare the cans well before painting. I try to use those cans as much as possible and for the rest I use the old airbrush.

also clean the spray nossel after each use. This will prevent it from clogging up the nossel which sometimes is the cause of the splatters

Hey ASre you sure they are air bubbles?? Not fish eyes?? Do you wash you model before painting?After all my prep and finish work is done on the body (after primer and everything) just before getting ready to paint i use a cleaner made for real cars the cleaner removes oil and dirt but you can also wash dish soap (small amount) and water and rinse very well.. then only handle the model with lint free gloves on.. Paint is very fussy if there are any oils on the surface it will reek havic with the paint and it will look somewhat liek air bubbles.. Hope this helps ya somewhat.. Later Rick

Its not the testers paint.. I use testers my paint comes out great.. It dont matter how good your paint is if your doing something wrong its ganna look like crap.. I have seen models painted with 99 cent wally world spray bombs that are flawless and shine more then a mirror.. It all goes back to proper prep, proper spraying, and proper polishing..

Sorry, gotta to disagree here.

It all depends on the preparation. As long as you warm the Testor can first (a bit longer than Tamiya) the end result will look good.

OF course, Testor comes out in heavier spray and you have to take that into account.

Try spraying a Tamiya can straight from the cold storage and see what you get. Bubbles and peel. :silly2:

I agree...it's all in the prep. My very 1st car wasn't preped at all - no washing, sanding, etc - and altho I used tamiya paint - it still came out horrid!! :(

You know, if it makes you feel any better, after preaching about doing prep-work in my previous thread this morning I got lazy and decided to spray clear-coat from a semi-cold can and in multiple coats to (at one sitting!!!). The result? Heavy orange peal... :crying: :crying:
And I mean seriously heavy peel...

Time to bring out the sand paper...

i wus painting the last 2 coats of my RX-7 FD3S today...and i wus using the techinques u guys posted, this time, i got a really glossy coat with minimal airbubbles and orange peels...but 2 factors fucked up the kit:
1) there are huge drops of paint on some parts (not very noticable)
2) the gray primer....the white tamiya just didnt cover all of it, i'd say it covered about 90%, i added like more then 3 layers, the panel lines are still gray-ish and u can hardly see them nemore....

wut i learned: well atleast now i got glossy body hahaha next model, dont paint anything white w/o a white original coat hahaha

1) Possible cause of the problem is either the distance to the model was too close, or the nozzle was dirty. After paint is completely dry, use small piece of fine sand paper (1500 or above), and smooth it.
2) That's why both Gunze and Tamiya have white primer. Also, DupliColor has good white primer.
