Information 

A 1-2 mm surface coating of adhesive residue is required to help new adhesive to stick.

Keep cut surfaces clean and free of grease and do not clean with cleaning solution.

If there is no longer a surface coating of adhesive residue (e.g. during body repairs), the affected area must be cleaned and treated with primer before applying adhesive.

Adhesive must never be applied to an unprimed surface.

Likewise, primer must never be applied to the adhesive residue.

Activator must be applied to the bonding surface after leaving it for more than 2 hours.

Information 

The roof has a total of 26 spacers and additional foam pads for adjusting the height.

The spacers are not supplied with the new roof.

The spacers must be selected according to the colour marking of the old roof and must be fitted at the designated positions.
