Best Water Repellant For Cabriolet Top?

I live in Oregon and well, we do get rain here. I'm wanting to treat the top this summer with a water repellent. What is the best one forums members have found? And what about the new repellent from Rustoleum?

Raggtop works pretty well, but not for long. Maybe it's the killer Florida sun. That being said, I haven't found anything that works better.

There was a u-tube (I think) of a guy spraying 1/2 of top with ragg top and other half with 303. Both looked about the same with water sprayed on them. Main complaint about ragg topp was fine spray the bottle put out. I used 303 sprayed on with a cheap sprayer I bought at Harbor Freight, although the 303 pump bottle worked pretty good. Next time I will try brushing it on.

I used the AutoGlym system, and have had great results. I am just north of you and get the same weather so I understand how important it is.

I have sprayed on the 303 product and brushed on the fabric protectant from West Marine. The West Marine product caused water to bead up in larger droplets and the protection lasted longer. It is also cheaper and can be found on sale occasionally. I liked it so much I went back and bought another gallon. (It may be a long time till I need the second gallon). It was on sale for less than $35. I believe regular price is over $50 a gallon. Brushed on two coats all over and finished with a third just on the very top area. I live in Seattle.

I used 303 and brushed it on with a microfiber sponge type thing. Yes, you will use more product, but it ensures and even coat. Water just runs right off. Love it.

I tried 303 for the 1st time today. Word of caution, cleaning the glass from overspray is brutal. Had to use ammonia to rub it clean. Now I know why others roll or sponge it on.

Gtechniq I1 Smart Fabric

I've had great durable results with Gtechniq I1 Smart Fabric which provides a hydrophobic protection.
