Arrrrrgh varnish

[Irishaernut]

Ahhhhh what happened????
How can I fix it??

It was humbrol clear painted on indoors in a fairly warm room.

[iainpeden]

Mr Muscle oven cleaner and start again

[Irishaernut]

Will that remove the paint as well?? Or just the varnish

[ArabJazzie]

I recently read something on Britmodeller where someone had this issue. However, i cant remember how it was recovered, but certainly not a strip down. Have a look over there to see if you can find the thread, maybe in the group builds area.
Arabest,
Geoff.

Paint as well I am afraid. I have had a similar problem in the past and tried white spirit to remove the "bloom". Afraid it just came back.

[Fumbles]

I'm not familiar with Humbrol paints.. I only use Acrylics... But I had a same kind of thing happen years ago... Again with acrylics.... but it may work with this. I wet sanded back to a smooth surface, touched up any paint here and there with the air brush. Then used a new bottle of clear which brought the dull sanded paint back to a shine.

If all else fails and you have to do a complete strip down... you'll be able to get rid of that finger print in the wing though.

[Irishaernut]

Thanks Iain Geoff and fumbles. I'll looking britmodeller then try the others , and I just noticed the awful seam and the you spotted the fingerprint.
Man it's bad probably better to try again .

I have used Mr Muscle oven cleaner to strip an old model (no smutty jokes please) which had been painted with a mix of Halfords acrylic and Humbrol enamel. Take the kit outside and spray liberally with the foam cleaner - best to wear plastic gloves - the put it in a carrier bag and leave for a few hours. Then wash everything off - using an old (therefore) soft) toothbrush to get into the fiddly bits. Again - I do this under the garden tap.

Make sure you take the canopy off before you do this.

Good idea to try it on an old model first just to see how you get on.

looks weathering sort of

looks weathering sort of

I was thinking that, but perhaps slight overkill, as if the aircraft has been abandoned for a year or two. Maybe put the model in a diorama by a hedge, with tall weeds growing up around it, panels off, etc...

Can you not just use a very fine sanding/polishing stick to remove the top coat of varnish?

[Irishaernut]

Right guys I looked online and in going to try them in the following order

1- heat gun or hairdryer
2- light sanding,
3- alcohol wipes
4- gloss cote
5- oven cleaner

We will see .

[Irishaernut]

Well I think I fixed it.

I tried all the options I found online before going for Iain's nuclear option.

1.hairdryer = nope but maybe you need a heat gun or to do it ASAP after clouding.
2. Alcohol wipes = not really good.
3. Sanding = started a test patch and then nearly lost my mind.
4. Gloss coat= went for a spray of tamiya flat clear and it seems to have worked.



Thanks for the help, back to the wip

[Maisie]

I was going to suggest just clear coat it again, 9/10 it covers cloudy marks like this, as it livens up the old varnish and covers it... No need what so ever to strip back, always try covering it again first as you have nothing to lose apart from some varnish.

Never use a heat gun either on plastic, always use a hair dryer!

[Irishaernut]

Thanks masie , I used the hair dryer but it didn't work .
I'm going to paint on a gloss coat now before applying decals I hope I don't get any more reactions.

[Domvickery]

I'd say to cause a reaction like that the surface wasnt clean enough before spraying the clear

[Maisie]

Brush on Pledge Klear, self levelling and polishes up nice, no need to spray..

[Irishaernut]

I have humbrol gloss clear to go on, will that do the same trick?
And I say your right as I didn't really clean the model beforehand.
What do you clean you model with ?
Is it just soap and water or do you use a particular cleaner?

I'm basically missing the basics

[Maisie]

I use baby wipes lightly but if the paint job is rough you will get fibres on the model which are a pain to get off, if the model is glossy then you shouldn't have this problem, just on a matt surface you will. I very rarely clean a model though, I just handle it carefully inbetween paint jobs.

[Irishaernut]

Thanks, yeah I need to find a spot where I can build models. At the moment it's sitting on my couch with cat and long haired girlfriend, so it's impossible to keep a model hair,dust and fluff free.

And when I spray I just stand out on the patio which has its temperature and humidity implications.
Thanks for the advice , it will all improve what I'm doing.

I used a hair dryer on a stork when I was a kid to dry the paint. I lined it up at the front turned it on and trotted off to the toilet. When I came back the stork, well, err was a very different shape to the way I left it. Undercarriage was now bent up level with the fuselage and the wings bent down to the floor in a symmetrical way. It looked like a banana . sort of liked it and kept it for years

[Irishaernut]

Brilliant Rob, yep I have had a few models as a kid that were a bit Frankenstein but i loved them.
I also added "battle damage " on some models.
Including a Palestinian p-47 which undercarriage broke so I made it a crashed aircraft.

[rob68]

Also had a revel Ju88 hanging from the ceiling when really young, about 6ish, anyway was playing undedneath it with train set and happened to look up just after the drawing pin gave way and can still remember it in flight until it didn't pull out and made contact with one of those huge two tone round hoovers. The hoover won.

I know absolutely nothing to do with original post but just sprung to mind

[Irishaernut]

Yeah back when you would build your model then play with it, I was very careful with all of them but sometimes I'd get a bashed model or one that broke like the ju-88 you had and "test" them.
I once shot a 1/48 scale mirage2000 off a piece of guttering to test the firework motor I had shoved up the fuselage.
It flew really well until the inevitable explosion, which looked amazing by the way.
I might buy a 1/72 version to recreate that

Cheers Steve

Lol I tried that with a corgi flt bed lorry, think had 6 mini rockets on the back and if didn't move, set on fire though. Seem to remember the matchbox walrus flew really well with the wings covered in toilet paper which I'd accidentally spilt turps on and accidentally struck a match new to. I rather quickly had to chuck it out of the window in the dark
