Had a ant infestation in my van and roadblock fixed it immediately

Brian Williamson
Roadblock ant and spider spray

This product seems to be effective but caution should be exercised if your entered use is on an item that has been painted with a mineral based paint. Such as mineral based spray paint. I tried it on a a sample surface before using the product on the particular surface and found that the product appeared to dissolved and blister the surface of the paint.

Hi Brian, thank you for this feedback. Firstly, it is so great that you tested the product first but just wanted to understand a little more by what you mean by a mineral based paint as our advice is that mineral based paints are not typically used in automotive coatings other than in undercoats (which would not normally be exposed to RoadBlock). Just to confirm, RoadBlock has been tested on all paint surfaces but we might reach out to you directly just to understand more about your situation. Thanks again for your feedback and the helpful review!

I have not used it yet my wife brushed off the cobwebs so I have to wait until they come back. HOWEVER, I would suggest that Autonomy give concideration of changing the delivery tube to a flexable type like the WD40 has.

Thank you for the feedback. Will def take on board.
