Excellent product.
This was recommended by the contractor that just put a new coating on our houseboat. He suggested that we not use dishwashing detergent on the new surface. This was one of the washes he recommended. Used it today and it worked as advertised. All pollen gone, all dirt removed, looks good.

Great soap!
I like using Meguiar's product and this one didn't disappoint. I used it on my new boat and worked as it should. I would recommend it especially when it's on sale.

Excellent Fiberglass wash.
This was excellent wash I used it on my RV which as a fiberglass shell and it removed the dirt and black streaks better than any of the other car washes I've used, even worked better than the wash "Made Exclusively" for removing those streaks by another manufacturer.

This Soap Turned My Swamp Monster Boat Into a Yacht With a LinkedIn
I bought this because my boat was looking like it had been marinating in swamp juice and bad decisions. I’m talking full “found at the bottom of a lake in a horror movie” vibes. One wash with M43 and suddenly my boat looked like it pays taxes and has a LinkedIn. First of all, this stuff foams up like it’s training for a bubble bath commercial. I hit the hull with it and the grime started sliding off like it didn’t want the smoke. Bird poop? Gone. Mystery lake slime? Evicted. That weird brown streak that’s been judging me for three summers? Sent to another dimension. It smells way better than it has any right to. I was fully prepared for “industrial chemical that dissolves fingerprints,” but instead it smells like responsibility and a fresh start. What I love most is that it actually cleans without stripping everything like you just power washed it with regret. My gel coat still beads water like it’s flexing. No chalky nonsense, no sad faded look. Just clean, shiny, and mildly threatening to the next seagull that tries something. Used it on my buddy’s RV too because he said, “It’s fine.” It was not fine. It looked like it had driven through three states of pollen and one biblical plague. M43 handled it like a champ. Now he thinks I detail professionally. I do not. I just read the back of a bottle and commit. Is it dramatic to say this soap restored my relationship with my boat? Maybe. But I’ve spent more on worse decisions that didn’t make my hull this glossy. 10 out of 10. If this soap had a fan club, I’d be treasurer.

ULTRA MEGA CONCENTRE, et très efficace
Alors, moi je n'y croyais pas. La notice indique un pourcentage (qu'on traduit en litre car c'est indiqué en galon) extrêmement faible. Mais si, c'est bien de l'ultra concentré. Il suffit d'en diluer très peu pour être efficace. Je recommande!
