Hi guys
i was wondering if it’s okay to spray tamiya over top of Vallejo surface primer after the primer has dried hard after a couple days
thanks for any tips

I doubt it, but test it on some scrap plastic or plastic spoon first…
I did it once with some small camo spots of XF-64 over a basecost of Vallejo RAL 7028 primer with no bad effects.
Been the experience of some here that you pull the underlying color. I’ve heard enough bad experiences, I’d never use their primer.
I give the model a light scuff with a grey scotchbrite pad, then primer with Tamiya, lightly scuffed again before color coats, usually with a used one.
Grey pads can be had at most big auto parts stores. Cut down with scissors
I’m happy with the primers I use thus never tried the Vallejo. But I’ve investigated their primer and ran right into suggested dry time of at least 24 hours. And so I have to wonder if many of the problems we read of or even see in videos, not enough dry time was given.
That said, why ? I mean Stynylrez is ready in about 30 minutes plus is sandable and a sealer, Mr Primer Surfacer in perhaps 10, Tamiya similar. So why even go the Vallejo primer route with it’s delayed dry times and questionable history ? The only reason I can think of is someone unknowingly bought into it, assuming it’s like any primer when there are proven better options.
One problem for me even if it sticks under the ideal conditions, from what I’ve seen of it is it scratches and pills up when trying to sand it. It’s really a non sanding primer surfacer then. That’s pretty much useless to me right there.
doubt that it would be a problem ?
Thanks for the tips guys, in my area all I can find is the Vallejo stuff
I wouldn’t recommend it.
Vallejo surface primer is so bad that you’ll wish you’d ordered a proper primer online.
As I mentioned above,I used their RAL 7028 primer as a basecoat for a couple of models and it acted no different then Vallejo Model Color paint,I put a Tamiya camo pattern on it,used a wash,and weathered it.
I know that you can’t sand it like good primer but it worked fine as regular paint.
Greg, I’m still with Stynylrez as my primary primer. And just bought into Mr Primer Surfacer for when I want to shoot lacquers. Both of which my local guy doesn’t carry. I haven’t bought primer locally, only online for about 8 years now.
That said and I know you know, I find Stynylrez to have a good bond to plastic and paint to it, even craft paints. My issue is sand scratch swelling with hotter lacquers so thus the Mr Primer which is lacquer. I find it has even a bit tighter bond to plastic than Stynylrez. I haven’t gotten to the test yet of sand scratch swell but fully expect it to pass that.
For the OP: I wouldn’t mess around with a shaky primer as it’s the base for the entire painting process. If your primer lets go your whole paint job is trashed.
I’d say we are in agreement, Anthony.
I concur that Vallejo Primer acts just like Vallejo Model Color, and as you mentioned, that is fine so long as one is not looking for ability to sand. And I would add or mask, cure to a hard durable finish, or adhere very well.
It lays down like a dream, pops surface detail and self levels as good as I’ve seen.
And just so I’m not misinterpreted, Vallejo is still the paint I have used the most in my past decade of modeling, and I still like it. I’m not Vallejo-bashing in any way.
I use either Tamiya FSP or Mr Fine Surfacer as primer. It gives you every option for a finish coat selection without worrying about turning your hard work into a gummy mess right at the end.
OMG,
I don’t think I’ve tried a lacquer over a stynylrez-primed surface that I’ve sanded, so thanks for that input.
I wonder if, now that I finally have a properly vented booth, if I will find myself using good old Tamiya rattle-can primer more. Hard to beat the performance and simplicity of use. [2cnts]
Cheers for the help fellas i appreciate it
