Rock solid adhesive for fibreglass to metal bonding
Used it to bond fiberglass to metal, and it holds rock solid with no movement. It’s flexible, strong, and durable, perfect for automotive applications.Pros: Excellent adhesion, great for metal and fiberglass, long-lasting bond.Cons: Messy to work with—wear gloves, as it’s hard to clean off hands. Keep thinners nearby for cleanup.

Brilliant
Excellent. Goes on well and sticks really well

Good strength
Worked as described. Noticeably different from 522, as it has improved strength and a degree of shock absorbance
User
Superb product.
Not cheap but very good product. You have to work quickly or you will spoil the finish. After a little practise I was delighted with the how well it held my wind deflector to the from of the camper van roof. Worth every penny. Tip. Reseal top with insulating tape stretched over noozle and it will save the unused product longer.

Fantastic stuff, but you have got to be quite handy with a mastic gun cause it can’t get quite messy always use masking tape to create your straight line

Good, strong adhesive for fixing awning rail to Motorhome
Wanted a second awning rail below my Fiamma roll out awning to affix my new Kampa awning (to avoid all the creaks and rattles in windy weather).Worked a treat and easy to use - solid hold without the need to use any screws or bolts through the MH side walls.Good 'grab' and quick setting - left for a couple of days before using the new awning rail in anger - gives a far better seal for the awning against the MH too as opposed to using the channel in the Fiamma.Very happy with the results and would recommend for this usage.

Sa réputation n'est plus à faire
Il me fallait une colle spécialement conçu pour la fixation de mon support de panneau solaire inclinable.Celle ci rempli parfaitement son rôle.Elle s'applique comme du mastic sur une surface propre et dégraissée puis il faut bien respecter le temps de séchage environ 8 jours pour que le produit soit complètement sec à cœur.Je vous le recommande
