Product Review: Mantis Scratch Repair Pen

Mantis Scratch Repair PenDisclosure: I received free review samples from JML for the purpose of this review. I received no payment and was not required to submit a positive review.

When I was a child, my father was fond of telling me that if something seems too good to be true, it probably is.

I had cause to remember this recently, when JML sent me a Mantis Scratch Repair Pen to review.

On the pack, it claims to provide “Instant Bodyshop Clear Coat Fix” and asks “Why pay for expensive scratch repair work?”

I decided to put the Scratch Repair Pen to the test and find out whether I’ve been doing it wrong all these years…

Instant Clear Lacqeur Coat

The Mantis Scratch Repair Pen (RRP £9.99) can be used on paintwork of any colour because it contains a clear lacquer which fills up scratches in your paintwork and then dries hard, providing a protective, waterproof layer.

The pen itself is simple to use:

  1. Give it a shake
  2. Depress the nib to get the liquid flowing
  3. Draw a line over the scratch
  4. Wipe away any excess

Make sure the paintwork where you are applying the pen is clean – otherwise it will smear horribly when you wipe away the excess.

Other than this, it is just as quick and simple as it sounds – so what where the results like?


When you wipe away the excess, it is hard to avoid feeling that you are wiping away that liquid that’s in the scratch, too. I figured that some of the liquid would be left in the scratch and would work its magic as it hardened, which takes up to 48 hours.

I left it to harden for a day and then went back to have a look.

It’s hard to tell from the photos, but the results were a mixture of good and bad:

Good – the clear coat seemed to have filled the scratch and hardened – when I ran my finger nail over it, I could hardly feel it anymore.

Bad – the Scratch Repair Pen did very little to disguise the scratches I used it on. They just look a little blurred at the edges.

The conclusion I have drawn from this is that the pen will provide some level of protection and sealing for damaged paint, but is not any use for cosmetic repairs, as it does not disguise anything but the finest of scratches.

My other concern is how long it will last – has it really hardened and bonded with the paintwork or will it gradually wear away, leaving the scratch exposed again? Verdict

Pros: Very simple to use. Does seem to fill in scratches and harden.

Cons: Does not conceal scratches – they are still visible after treatment. For very fine scratches, you are better off buying a good quality polish or paint renovator. For more serious scratches, you will need expert assistance if you want them to disappear.

    Perhaps a little late but this is a very bad product – it needs 48 hours to cure. During that time dirt will stick to the liquid leaving snail trails all over it.

    Has anyone found a product which removed this? Otherwise looking at the amazon reviews most people with silver cars have to respray them.

    Hi, can anyone help., just managed to use a cloth containing Mantis Instant Shine onto the windscreen of my car. I’ve tried most things to remove the smears from the glass but nothing seems to work.

      Not sure what you’ve tried, I’d suggest a decent quality glass cleaner, either an automotive one or else windolene.

    Does the mantis pen go off, I’ve used it and after a week or so it seems to have disappeared, I have had the pen for a few years.
