Trying a new primer!
Posted by Anonymous on Sunday, October 17, 2004 6:48 PM
Hi Guys.

Seen recently a new tip for primer that will stick to most materials and will NOT be affected by most paints.
Reportedly it can be either brushed on or sprayed trhough an airbrush.

The stuff is called GESSO available from most arts supply stores, comes in a variety of thicknesses and colours(clear too), thins down with water and I think has little to no smell.

Apparently according to my sources once it is stuck on a kit it won't come off and will provide better paint adherence than standard model primer.
Said that the tip comes from large scale fogure modelers so it might not be suitable for certain kits/geners.

Just thought I am going to share the tip.

P.S.: I am heading later on to the Art supply store to get some of it to try it out.

People who build vinyl figures have used Gesso for years because most paints will not hold on them. I believe it was origionally developed for artists to seal the holes in their canvases prior to painting. If that is true, what will it do to the surface detail on a model? Most vinyl models don't have the detail that our plastic models do after all. Give it a try and let us know what you find.

I think artists dilute theirs very little, the recommendations I were as follows:

Thin with water and either apply 3 thin layers by hand or airbrush it on, now I am already airbrushing my current primer so I will let you know what the difference is. Reduced smell alone would be a blessing to the family. Wink [;)]

I will try it on a 1/72 Robot kit first and see how it goes, it is of interest to me as I have got quiet a few(50+) Vinyl & Resin kits(Robots, Figures 1/8~1/4 scale) in the stash and it would save me quiet a bit of cash and hassles.

Just thought it might be of help to some of the other guys here.

Gesso is mostly used by artists to seal their canvass before oil painting. I've used it as a scenic medium for dioramas, but never tried it as a primer. It may be fine on Vinyl kits, but I wouldn't use it on aircraft kits.

Try on Silver color. Choose on the smallest pigment any brand. It can seal any color and easy to cover. I always use Gunze Sangyo Acrylic No. 8 on Aircraft or Tank. Trust me you will like it.

MM, thanks for the tip!!! I prefer to use solvent-based paints and always had trouble with the paint cracking and flaking off vinyl tracks. I picked up some Gesso and airbrushed two coats on a set of tracks (thinned with a water / alcohol mix - about 4 or 5:1) and after my painting routine with enamels, the paint shows no sign of cracking; even after bending them double. I'm pretty jazzed, to say the least. Big Smile [:D]

Gesso is now my primer of choice for vinyl (or any questionable material) and though I will still use solvent-based primer on styrene, I would not hesitate to use Gesso. As thick as it is, it takes a LOT of thinning to get it to AB consistency, but once thinned it sprays easily and does not bury detail.

Yeah, it takes a lot of thinning and a bit of getting used too.

Glad that it worked out for you.
