PROTEXWorld Convertible Soft Top Canvas Waterproofer 1Ltr. - Seals & Protects

Made my top look like new.

Just had enough to do the canvas top of my convertible Toyota solara

My Saab 9-3's roof announced that it was no longer interested in keeping rain out after eleven years of service, when the rainy season started in CA last month. I was horrified to see drips coming from both the driver's side and passenger side from the edges of the roof, and booked an appointment to see a car upholstery specialist. Diagnosis? "You should get a new roof. That'll be $3000."I thought it was at least worth trying to get a couple more years' service out of the current roof with a sealant, so I gave this a try. Early indications seemed promising: the roof was clearly beading up with water rather than absorbing it (see photo) and after the first rain shower it was easy to see the patches I'd missed with my initial treatment of the roof (see other photo).The acid test was a drive up the country from southern California to northern Washington. In total I went through seventeen hours of driving rain. No evidence of any leaks.Pro tip: as well as having lost its effectiveness as a moisture shield (prior to the treatment) it was also sagging in a few places, meaning the water pooled when the vehicle was parked instead of running off. I stuffed some of those postage/packing air bags into the space between the roof and the headliner to restore the shape of the roof. Seems to have worked very well. Long thin balloons might be an even better choice. Just remember to take them out before it's top-down season again.

A bit challenging to apply because it's quickly absorbed and therefore difficult to spread out. One bottle is barely enough for a BMW 1-series small top on a first application (manufacturer recommends 2-bottles). Once applied, results are spectacular: top fabric layer is completely waterproof and water droplets run down without wetting it... Making it harder to wash the top too :-) Not sure about how long it lasts but after 3 months, no issues.

I waited a little too long to seal my Camaro top. I tried a local highly recommended brand, however I was getting a few droplets of water in the early mornings. I decided to try Protex Waterproofer. I used a paint brush and took my time. My top absorbed the liquid like a sailor on shore leave hitting the local watering-hole. The next morning and every morning since, no more leaking, unlike the sailors mentioned above. I'd highly recommend Protex Waterproofer. Word of caution, make sure you roll down your windows and cover your front and rear windows. I got a little splatter from the paint brush on my back stroke on the front window, but didn't notice until the next day. Used Goof Off to clean the window.

I applied it to my convertible top on my car. It didn’t leak before but the top was getting a bit old and I thought extra protection wouldn’t hurt. I washed the top with a non caustic cleaner the applied the product to the top with a brush as directed. It went on easily enough. We just had a heavy rain but the water didn’t bead up as I expected but the top still repels water. They recommend 2 coats and I only applied 1 so maybe that’s it?

Works really great - water WILL bead up on your rag top. 2nd time using in 3 years. Word of caution - mask your paint and glass well. Use painter’s tape + newspaper. If this stuff gets on those surfaces, and you miss it, and it dries, god help you - this stuff is so tuff, it’s not coming off!!! I learned the hard way, and after 3 years, it is only starting to come off the windows. Go VERY SLOW, in painting it on - really slow, like dabbing it on. On vertical parts of the top, it has consistency of water, so will run off!!! Take my advice and MASK.But it really is a great protectorate “re-weatherizer” for rag-top convertibles.

Before using this product i had water pouring in my car in a rain storm. After using this product no more water in my car. Two rain storms and all is good after just one coat.
