hello-ok so after they do a pressure test how do they go about sealing.......they seal from the inside out while it is presurised so the sealent will be pushed into the leak or do they just seal from the outside and just get 1/2 of the leak?
It's impossible to seal the leaks from the inside without removing the interior skin etc. We mark all of the leaks with a grease pencil then wash all of the soapy water off, along with the road grit. Blow off the areas that are marked & make sure they are dry, then apply the sealant (I use Vulkem). It's a good idea to wait over night until the sealant is dry, then recheck with the Sealtech.
