Please get AutoShine - it works - link

Seems to be varying responses on this autoshine product. I have sprayed on the swe rat spray on mine.

I think the cats are the best solution. Put some food around so they kind of regularly hang out in the area and hopefully your automobile is safe.

Man, with electric cars coming with everything running probably only on wires, rats are gonna have a field day!

After 2 months of 3M rat repellent treatment:

Call it sheer luck or the effect of 3M, here are the results. Would give the benefit of doubt to 3M as footprints seen on the engine bay but no damage done yet.

It is the same situation with mine.

Got the coating done almost 2 months ago, but the rats still enter and leave their eatables around, but nothing damaged. I hope it remains like that since the car will be idle for 3 weeks next month.

Hi Friends ,

I have almost always faced this issue of rats seating in engine bay and littering around. But some days back it was the first time that they did some damage. It ate out a big portion of the dampening inside the bonnet. Obviously I was furious and immediately rushed to 3M in worli Mumbai. I got the rodent treatment done at the 3m outlet for Rs.1100 . The staff was helpful and friendly but also little skeptical whether it can really keep the rats away. After the treatment almost for 10 days it kept the rats away but now they are back. So in short this is not working. It seems even 3M can't save us from rats.

Question here is after the 3M treatment were any wires damaged due to rats?

3M personnel says it will not prevent rat from 'visiting' the engine bay, but will not cut any wires as the coating repels them for doing so.

The 'Autoshine' spray that I use is liberally applied on the insulation & dampening too (both, under the bonnet and on the firewall). Did 3M do the same?

@GTO - I also use the "Autoshine" spray - so far the experience has been good. I also had a chance to talk to Mr. Parag of Autoshine last month. While it could be "advertising", he did mention that the 3M spray was sprayed very haphazardly by the 3M folks. Furthermore, the customer is forced to have the 3M guys spray the car when buying the spray and will not sell the can directly to customer without having the 3M guys spray it. Also, the spray is more expensive (quantity wise) than the Autoshine product.

All this sounds a bit fishy to me. From the posts, am not sure that 3M spray is entirely effective. The Autoshine spray seem to elicit more positive comments.

My only issue with Autoshine is that there is absolutely no indication on the can of the chemical composition (i.e. the ingredients) of the product.

Yes GTO , they applied.

I'd assume that a professional 3M staff member will apply it more carefully than an amateur car owner.

I agree. The smell is unbearable. I don't use the car for 24 hours after its been applied.

Damn, then its confirmed that the 3M spray doesn't work. Yours is the 2nd or 3rd failure reported on this thread. Please try 'Autoshine'. It sure seems to work!

I like the smell of autoshine, smells very ayurvedic / herb'ish We have been using this for last 1 year after GTO recommended it. So far so good and of course, we now have two semi domesticated city cats guarding, around the parking place.

Friends

I use 10 Rupees worth of raw tobacco strips which I buy in a nearby Indian medicine shop tie with a cord inside the engine bay and change once in 6 months, its been effective, rats stay away till the tobacco smells strong. Sanjeev V S, Bangalored.

I recall somewhere on TBhp reading about a BHPian (who was having problems with rats in his engine) who sprayed Autoshine on his engine and actually waited in his building's basement during a night (or a few nights) to observe whether any rats came.

Well - a rat came but instead of jumping on the wheel and into the engine, he said that the rat stood on its hind legs, smelled around and moved away.
So, something apparently works in the formulation.

Hahaha! That would've been a sight and trust a BHPian to observe that.

My take is that rats still enter the engine bay (have seen marks), but they don't bite the wires sprayed with AutoShine.

Hi friends. Just saw this on Instagram and thought of posting it here in case anybody plans to get the treatment done on their rides.

P.S- I have no commercial interest in 3M.

An update. I spoke to the 3M franchisee owner Mr Sheshadri who had initially sent me the flyer regarding the Rat repellent coating and updated him of the ineffectiveness of the coating as confirmed by few BHPians. I had forwarded him the thread link for reference purpose only and he has taken the issue with the 3M people. Mr Sheshadri also confirmed that out of 600+ customers in Thane who opted for the 3M coating, he has recd one complaint till date but that was regarding smell and not any due to rat tamper. He was of the opinion that application of the coating is the key to the effectiveness, this explanation is debatable actually. Mr Sheshadri is going to update me of any response recd from 3M people.
