Chipping woes

[Jolly Roger]

Steve.
Surprised you don't then set fire to it , I know I would:nerd:

Hi John. Based on all the replies here I suspect I didn't give it enough time between applications. Maybe I'll stick a couple of 'L' plates on the Stug. :rolling:

[Jolly Roger]

I use the cheapest hairspray I can find. Sometimes I just give it one good spray. Other times I decant and brush it on wherever needed.
I normally let it dry overnight.

Hi Ian. Do you decant into an airbrush at all, besides brushing it on ?

[Jolly Roger]

Hairspray does it for me, never used anything else but I always use Tamiya acrylic paint, just an old man stuck in the past. :smiling5:


Andy.

Hi Andy. I have never used Tamiya paints. Having a fair range of Vallejo paints I am reluctant to purchase other brands.

[Jolly Roger]

As mentioned, the paint has reacted with hairspray.

Primer coat, leave for at least 24 hrs to harden.

Hairspray, leave for 24 hrs to set.

Top coat, always do a patch test on the model, normally underside.

Then chip away.

Finally, varnish coat.

Hi Si. Yes it seems you are correct, based on all the replies, including yours. I like your idea of testing on the underside of the vehicle. Must remember that one.

[Steve Jones]

That is an interesting thought " spraying at arms length". Any reason for that idea ?

You have more of a chance of getting the fine mist rather than heavy droplets nearer to the spray nozzle

As Steve points out airbrush distance and pressure can affect the coat. I tend to do a 50/50 mix of paint and thinner and see how that goes. Generally I do around 20psi and adjust the needle nozzle for a finer or wider spray area. Depends on if you want mist coats and build up or are after a detail line etc. And yes, even that can and does go wrong.

[Jolly Roger]

Well that makes sense. Thanks Steve and Si.

Touchy subject one mans poison and all that ,I think perhaps your problem could well be one of thoes modeling phenomenon you could do the same again it would never happen ,HS I think gives the best results at 35th the models are huge and can take a whole lot of scrubbing giving some amazing results ,working almost all the time in 72nd CF is the only way to go ive used CF with mixed results , I would recomend going on YouTube and stick in Michael Rinaldi some of what he does with the hair spray goes against the rules and he's pretty nonchalant about it well worth it.

Just remember when watching youtube videos, there's a time lapse in between each process which is cut shorter by editing or if there is a live audience the presenter would have examples prepared ahead for each process. So the key is not to accomplish in one sitting but if you're impatient then use a hair dryer. :smiling2:

Cheers,

Hi Roger
You asked me a question way back on 19th May. I am really sorry I missed it. Very remiss of me and bad manners as well. Please accept my apologies.
The chipping fluids I use are these. They all give a slightly different effect and some require more effort to chip than others. If I had to stick to one it would be Worn Effects.

Once again sorry for such a late response.
Jim

It simply isn't dry enough.
The HS, the paint.

I actually use the 'crazed paving' effect on Pacific aircraft (mainly Japanese) on parts of the wings.

To do this I specifically painted it when the HS was finger touch dry on the parts I wanted the crazed effect.

The rest of it I allowed to dry normally.

Otherwise, leave it overnight between coats and it'll react fine with usual wet brush application.
