Robust marker pen for plastics

Dec 07, 2024 Last reply: 1 year ago 19 Replies

As usual, too many options and unclear what I should be searching for.



The primary use is a couple of control dials on an air fryer. They have black dimples on a black dial and so are pretty much invisible. I would like to put a dot of white our dayglo paint on them so they are easily visible. It just needs to be a very small blob so a fine tip on the applicator is required. I assume some kind of paint but waterproof.



Would Tipex be suitable? The applicator might be too large, though.



Humbrol enamel applied with a cocktail stick? [Not that I have seen Humbrol enamel for 60 years or more.]



Suggestions of modern materials most welcome.



Cheers

I might suggest using any old way to apply the paint but using a careful tissue wrapped scraper to remove it from all but the dimples.

And a tissue dipped in solvent to clean up any messes left over

To my surprise Humbrol enamels are still available.

Around £2.50 from Humbrol (plus postage). Around £5 from Amazon (free postage through Prime). However metallic gold was £1.89 on Amazon Prime so worth a punt.

Hopefully this will do.

[Back in the day I used to have a box full. Does anyone still use these in DIY land? Also I would have gone to a toy shop to buy this, but has anyone seen one in the last few decades?]

In my mind I was visualising a pen style applicator, but stick with tradition, I guess.

Paint brushes/sticks for car scratches Random Ebay listing just showing the range available

Other ebay sellers are doing 100 of one type for under £4

Cocktail or match stick also works, possibly don't try and get the final result in one go.

I've found them useful for a couple of small jobs other than touching up the paint on a car.

Nope. My local one diverged from my interests years ago.

Online for me all the way.

Small squirrel hair brush and dob it in the holes

IIRC Humbrol is now water based acrylic.

Hard to remove with solvents. Needs paint remover to get it off.

Talc or chalk powder mixed with a small amount of epoxy resin.

Microballoons in epoxy make a very white glue/filler

I bought a selection of self-adhesive round circles, about 1/8 inch in diameter. They came in sheets about

6x4 inches and in various colours. (Rymans I think)

I had a sheet of yellow ones and use them on the air fryer and the microwave

That's what we've done with our Leisure Range a few years ago. A quick glance now confirms all 10 hobs/ovens/hotplates are off.

Not a problem with ours.

Thanks. Now strongly tempted to order some because they look so useful. Even though I have a solution. Nobody can have too many "may come in useful" items.

8mm is too large. 5mm looks about the smallest easily available.

Meanwhile my management consultant has pointed out that a white sticky label and a pair of scissors is far more DIY than ordering yet more stuff online.

Consider me suitably chastened.

I don't suppose you have access to a suitably sized hole or belt punch.

Edding paint marker?

Different tip sizes, different colors.

"The premium solution for marks even visible on dark materials

"Regardless of the surface, be it smooth like glass, rough like iron of a pipe wrench or sparkling clean like polished lacquering, you can mark it all with the edding 750 paint marker. With its highly opaque lacquer-like ink it specialises in labelling many kind of materials, even dark ones, making it a versatile marker not only for DIY enthusiasts.

"Furthermore, the edding 750 paint marker is waterproof and even heat-resistant up to 400 °C, making it the perfect companion for your workshop."

Thanks!

This would fit the bill.

So just my lack of skill in searching failed to find the item I was originally visualising.

As an aside: I found white and black paint markers, originally bought for marking, a useful touch-up tool for paint...

Its like the old Unix man pages. Once you knew what command to look for, there was all the information.

But no help at all in trying to work out which arcane two or three letter command was the one you needed.

e.g. $ man made No manual entry for made

$make love $ make love make: *** No rule to make target 'love'. Stop.

Sill available in many real model shops but those are fairly rare with large areas of the country not having a close one, unusually we still have a family Ironmongers /DIY /Haberdashery store in the nearest small town who still stock some Humbrol. Its fair to say in recent times not all former users are as happy with it as they once were, production was moved back to the UK in recent times and some claimed there were quality issues , changes in formulae to reduce VOC content could also have a bearing on that. There also a lot of competition from other brands plus many users now prefer acrylic rather than enamel. Humbrol do an acrylic range and a while back reduced the size of their enamel range.

If you want something like a pen applicator style paint it might pay to look at what military or wargaming modellers use .
