For some reason, black primers aren't sticking to styrene. Black is the only color I have an issue with. I allowed the paint to dry, overnight, as per instructions and sprayed straight oob. I have a bottle of Stynylrez,on order. If that doesn't work, I will delve into lacquers.

Is it failing to stick to all styrene?

I only tested it, on that area. However, I have had similar results with other builds. At the very least, it flakes off.

Curious: What are you doing with the painters tape? Are you deliberately pulling at the painted surface? What is the lower (brown) color? Was it pulled at as well?

Although Vallejo primer is not the greatest for its adhesion
especially if you are masking, that blue painter's tape is way too sticky for that application.

I have found that Vallejo paints, although great is some respects,
don't bite into plastic...they sort of glue themselves on and even if dry and cured
will sometimes lift off like a skin.

I usually mask with a narrow Tamiya tape followed by a wider
"FROGTAPE"....the yellow one(same color as the Tamiya.

The tape is available in hardware stores: Home Depot, Lowe's etc. about $8.00CDN for a 60 yrd. roll
and comes in 2 widths.

Don't use the green version...it is more sticky.

It has never let me down...never lifted paint.

Cheers,

I am trying to prepare a paint swatch table, so masking shades. The lower is Vallejo Red Oxide Primer and it does not lift.




I will look into Frogtape. My concern is that it will lift, after I lay paint over the top of it. I will spray another area and see if it lifts, with silly putty.

Just tried Stynylrez. Covers well. Dries quickly(10 minutes to be safe). Does not lift.

Alclad grey is nice. It takes 3-5 coats, but is pre-thinned and resilient.

Tru-Color Paint offers 2 primers: TCP-007 a dark gray primer and TCP-256 a light gray primer (for light colors like white, yellow, etc). Both adhere very well to polystyrene. Then use Tru-Color Paint masking paper. Specially made paper with very low tack gives very sharp lines when cut with a good hobby knife. After 2nd color pull off the masking paper at 180 degrees (as you should with any masking material) and you will get excellent results.

Yes, we keep coming back asking modelers to give Tru-Color Paint products a try to eliminate the issues you are having with other products. Note that you do NOT need primers with our metal colors - Aluminum, Titanium, Silver, Steel, etc. unlike other manufacturers. Save TIME and MONEY.

I'll just toss in my 2 cents on Vallejo's White Primer (73.600). Went on just fine, dried nicely. But it was rather rubbery when I tried peeling the masking. Then it stuck to the tape and lifted cleanly up off of the plastic Wish I could remember how well I cleaned the plastic before painting.

not sure it helps at all, but applying it in fine layers is what I have found works best. I am guilty of laying it on thick, and I have definitely seen positive results by using very light coats first and second coat....and hitting them with a hair dryer. I try to remember to wash the plastic first as well, but again, sometimes impatience gets the better of me.
