Seamus Posted January 3, 2010 Share Posted January 3, 2010 Afternoon all, Just a quick question for you. I'm thinking of giving Halfords plastic primer a whirl and was wondering if it would be OK to use enamels, specifically Xtracolor and humbrol, on top of it once I've got the model primed?

Andy K Posted January 3, 2010 Share Posted January 3, 2010 Yes! Just make sure it's fully cured though. Link to comment Share on other sites More sharing options...
little-cars Posted January 3, 2010 Share Posted January 3, 2010 Shouldn't be a problem once the paint has hardened, but as with all things like this, try it on a spare bit of plastic card first just in case. Link to comment Share on other sites More sharing options...

Cheers Shaun Works a treat for me. The grey is a nice colour to paint over, and the white primer has uses too. Just be wary with a new can as it comes out quickly at first. Oh. dries in no time too, just rather smelly so wear a face mask is my advice. Steve Link to comment Share on other sites More sharing options...
CornishRebel Posted January 3, 2010 Share Posted January 3, 2010 Don't. I only ever use the ordinary primer...an have had no problems with Humbrol, Xtracolor, Revell, Tamiya, Lifecolor, Xtracrylix or Alclad. the plastic primer is designed for car bumpers, which are ABS (Acetbrutrylstyrene...or something like that) and it is an 'etch' plastic primer..it eats into the surface. I tried it once...it ruined the model...and i threw it and the model away. Hope this helps, Phil Link to comment Share on other sites More sharing options...
Andy K Posted January 3, 2010 Share Posted January 3, 2010 Thats odd cos I had exactly the same result with Halfords ordinary primer, thats why I switched to the Plastic Primer. Link to comment Share on other sites More sharing options...
Seamus Posted January 3, 2010 Author Share Posted January 3, 2010 Thanks for the replies folks, interesting to see a conflict iin opinion Think I'll try the plastic primer first on a test model, see how that goes Cheers Shaun Link to comment Share on other sites More sharing options...
Scarlet Posted January 3, 2010 Share Posted January 3, 2010 Always use it and have never had a problem with it. Link to comment Share on other sites More sharing options...
Spence Posted January 3, 2010 Share Posted January 3, 2010 I use Halfords Plastic Primer on every model that I build and I've never had a problem with it - either reacting with the plastic under the paint, or the colour coats that I use on top of it. Hope this helps! Spence Link to comment Share on other sites More sharing options...
Happy Martian Posted January 3, 2010 Share Posted January 3, 2010 I'm in agreement with Scarlet and Spence. I've always used Halfords Plastic Primer and have never had any problems with it etching the plastic, and it works with acrylic or enamel paints. Can't say I've had too many problems with the regular Halfords primer either. Link to comment Share on other sites More sharing options...
beastieboy Posted January 3, 2010 Share Posted January 3, 2010 Good as gold for me, always warm though the can in a little warm water first, comes out a treat then Link to comment Share on other sites More sharing options...
jimbuna Posted January 3, 2010 Share Posted January 3, 2010 Only ever used it on acrylics...with no problems. Link to comment Share on other sites More sharing options...
stratcat Posted January 3, 2010 Share Posted January 3, 2010 I use both, the only difference I can see is the plastic primer costs more. (you can't get it in the bigger cans) Link to comment Share on other sites More sharing options...
Daniel Posted January 3, 2010 Share Posted January 3, 2010 Yep, every model I build, no issues, I also warm it up in water first. Dan Link to comment Share on other sites More sharing options...

chadders Posted January 3, 2010 Share Posted January 3, 2010 I've never used their Plastic Plastic primer, but I've never had a problem with their normal gray/white/red primers, and overcoating with either acrylics or enamals Link to comment Share on other sites More sharing options...
Karl Posted January 3, 2010 Share Posted January 3, 2010 (edited) Always use Halfords Grey or White primer on my models and have never had any problems with them - using either enamel or acrylic over them. It's not specifically designed for use with plastic, but is the bog standard one for priming after doing car body work repair. On a large model, I'll spray it directly from the can, if it's a smaller model I decant it so I can use it in my air-brush. When completely dry you might want to smooth it down with 1500 grit abrasive paper for extra smoothness - the same as you would if you used it for car body repair.

Mal Posted January 3, 2010 Share Posted January 3, 2010 I use the grey all the time, I avoid the white as I've had it peel, this occurred when I used it to prime resin parts. Malcolm Link to comment Share on other sites More sharing options...
blimp Posted January 3, 2010 Share Posted January 3, 2010 it needs to be applied thinly , build it up with several coats and let it dry (when it stops smelling ! + 24 hrs) - pooling or runs will let the 'hot' solvents attack the underlying plastic . been there , done that ! 1 Link to comment Share on other sites More sharing options...

Cheers Shaun Hi Seamus If you want to us a primer from Halfords, may I suggest their acryllic primer. It come in white and mid grey and goes on very well. Ive painted quite a few models usin this as an undercoat and had no problems whatsoever. Goes on like a dream and so far no problems with applying other types of paint on top. Hope this helps.

Stonar Posted January 3, 2010 Share Posted January 3, 2010 Always use the plastic primer with no probs. I've convinced myself that it gives a finer finish than the standard one but have no real grounds for this belief. Steve Link to comment Share on other sites More sharing options...
n.vodden Posted January 4, 2010 Share Posted January 4, 2010 another vote for Halfords primer Funnily enough just picked up one of the huge 500ml cans for £6.99 on the way home tonight. usually use Humbrol ratttle can grey primer, but for the Red Arrow i've just finished I wanted a white coat down, so picked up a Halfords can. Its good stuff, but the only criticism is it comes out very fast so in my experience ( only 2 models with it ) you need to lay it down in thin coats from a good distance. If you apply it too closely or too heavily, it pools up and runs very easily. Almost ruined the Hawk because of that! noticed just in the nick, but did have a lovely thick run down the side of the exhaust I had to sand back Link to comment Share on other sites More sharing options...
