Hi @Geo-Z,

Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you join us.

Depending on the width of the gap I'd suggest using a combination of Ableflex and Sikaflex Pro+. You'll also need a caulking gun such as this Paint Partner Aluminium Caulking Gun to apply the sealant.

It doesn't look like it is, but if the gap is over 10mm, you might have some trouble getting the Sikaflex Pro+ to stay in place. If this is the case, stuff Ableflex of a suitable size into the gap to act as a backing to keep the sealant in place.

Let me know if you have any further questions.
