Windscreen Repair Kit-Hang Test

Ian Sprigg • June 30, 2020

Here is the test, here is the vacuum

If you a buying a windscreen repair kit this is the simple test you should undertake. If it has a stainless steel body and creates a vacuum before you pressure resin into the damage you should be able to check the vacuum by hanging it on your finger with the vacuum created. 

If you have a plastic £3.00 screw thread injector which has no first cycle vacuum you will need super glue to make it stick to your finger!
