Could this be used to augment screws to fit mudflaps to a car? I'm wanting to get a good seal around the wheel arch.

This product is waterproof, UV resistant and a flexible adhesive - so, yes, this could be used as you describe. You WILL have to ensure the part of the wheel arches are clean and grease free prior to use. I would advise Isopropyl Alchohol wiped on the cleaned surface, let air dry and then use the Sika Flex either run a bead directly on the wheel arch or along the mudflap edge that will connect to the wheel arch.

Can i use this to attach a cable entry gland to my caravan roof? Is this a waterproof sealant as well?

In principle Sikaflex®-552 AT can be used for this type of caravan application provided common sense design rules are applied. However, cable entry glands are normally a rubber type material and achieving a bond to this can be difficult. It’s important some tests are performed with the chosen sealant on the substrates to ensure a good bond can be achieved and no other effects to the substrates are observed. Positioning the cable gland so it’s not in standing water (horizontal) would also improve the situation. Please consult pre treatment guide and relevant TDS prior to full works.

This can be used to do round camper van out door window frames and is this waterproof

Hi, no this is not suitable for your application unfortunately. Please contact Sika Industry Technical Support for further information.
