Evening everyone,
Im very new to this model building and I'm currently building a number or Bell Kit Rally Cars!!!!! Which I'm enjoying very much!!
Ive come across a problem when applying decals with Hymbrol Decalfix that the tamiya paint is starting to run off!!!
Should i be clear coating every single part?? or should it just be the parts that require Decals???

Thanks for taking the time to read this
Ill be very grateful of any advice given

Rgds

It might be the case that Humbrol decal fix is too strong for Tamiya paints? Humbrol paints are enamels and thus can handle stronger solvents... (decal softeners and fix are weak solvents, that I'm pretty sure about)
I'm using Tamiya markfit and it's ok-ish on Tamiya paint as long as you don't rub it too much...

It is a good practise to clear coat the areas you are going to apply decals on but clear coats can change the appearance of colours so the safe option is to clear coat the whole model.
If you're going to add a couple of layers of clear coat after the decals it's probably safe to just clear coat the areas for decals.

And to be precise, with clear coat I mean glossy, not flat varnish. It's much easier to apply decals on a glossy surface.

I've had issues with Decal fix eating into Tamiya paint, even with a coat of W&N Galeria gloss over the top. As Jens said, it might be too aggressive for acrylics.

I changed over to MicroSol & MicroSet for decals and havent had an issue since.

Me I would and do gloss coat all over, if nothing else it protects the paint from knocks and scratches while handling your kit when decaling.

Thank you everyone for you replys!!!
I've almost finished my first model
Learnt lots on the way and still need to learn more
Another question
When I start me next model
Should i prime, paint and lacquer every single part for the best results???
Also I'm using tamiya x22 with mr levelling thinner!!! I give it a mist coat and then 2 decent coats and the part is gleaming but I fancy it's dying off by the next day!!!!
What am I doing wrong???

Decalfix has a reputation for dissolving some acrylic finishes (paint and varnish). It works fine on enamels and certain acrylics. Could be that whatever Decalfix is made of is close or the same as what Tamiya use in their paints.

No need to do every part prior to assembly. I personally build sub assemblies and treat each to primer and then paint /varnish as required.
