303 Products (30520) Convertible Top Cleaning and Care Kit with Cleaner and Fabric Guard Helps Maintain Water Repellency, Protects Fabric Convertible Tops and Tonneau Covers, 32 fl oz

I had did some research and watched several YouTube videos on convertible top cleaners and sealers. After the research the 303 product appeared to me to be the way to go.So, I purchased this kit, along with the 303 brush, to clean and seal my convertible top.First of all, I use a lint roller to remove as much debris on the top as possible before washing it. Next I washed the complete car and then used the cleaner and the 303 brush on the top. Left it out in the hot sun to dry. The went over the top again with lint roller and removed anything that shouldn't be there. I taped up all around the top and taped off the rear window.I liberally sprayed the top with the fabric guard, removed the tape, and wiped off any over spray on the vehicle and placed it in the A/C garage and left is dry for 3 days. After the three days a poured a bottle of water on the top and it beaded right up and ran off the top, on the water test.Am not really sure how am going to judge how affective the sealer is (weather and UV wise) or how long the sealing will last, because the vehicle I used this on is kind of a (?) garage queen. It does gets used, but it's a fair weather car, sunny or cloudy days, no rain or snow and of course, it's kept in an air conditioned garaged!I have to say the cleaner worked very good. After sealing, the water beaded up, ran off the top like it should. So far I'm happy with the purchase, it did a good job and I will purchased again when need...on second thought I'll purchased another kit now before the price goes up.

Brush: Extremely soft bristles! Definitely easy on top material, but needed to use something stiffer in a couple of spots (very carefully!). Decent for light soiling. Good ergonomics.Cleaning solution: Did the job on a good condition, lightly dirty top.Treatment solution: This top has been well taken care of so hard to say how effective. Water beaded before application but did seem to do so more after. The many youtubes are pretty convincing however for tops in worse initial condition.One application of each solution was sufficient.Outcome: Squeaky clean with water beading. Satisfyingly black and fresh looking. Couldn't ask for more. No clue how well it works on a non-maintained top, but suspect there is no reason to buy more expensive products.Application Notes: I only masked the car's hard edges with painters tape. Wetted whole car BEFORE both cleaner and treatment steps. When flushing the cleaner, I used LOTS of water on top and whole car. Did not remove paint protectants which is a potential issue. The pre and post water deluge seemed to prevent that.When treating, I was extra careful about overspray by using a handheld cardboard shield (inside garage to avoid wind drift) and treated the top perimeter with brushed on liquid rather than spray.Avoiding full masking protocol saved a lot of bother and encouraged careful use of products.

It worked real good. I used it on my Mustang Convertible Top. Easy to apply with no problems. Will buy again. This is another honest review of mine.

Good Product. I used this on a grill cover about 9 years ago and just resealed it with a new bottle. While the product is good quality, the bottle arrived about 1/2 full after leaking. There was enough for the job so I didn't return it but was not satisfied.

Tried this 301 on my fabric soft-top 2-weeks ago. I was very pleased with both the wash and protector spray.

Looking forward to using the 303 product. My review is on the packaging of the product sent. The original box had the top torn off of. You can see this in the picture. It looks like it was a returned item and then sent out on my order. The manufacturer's box was in rough shape. Thankfully it was wrapped in plastic to prevent any leaks getting into the shipping box. Product: 5 star Packaging: 1 or 2 Star

Easy to use, should come with a soft brush. But worked great on convertible top

The cleaning solution worked well. It seems to be concentrated. I sprayed my top and it took some effort to rinse it off.One issue I had with the fabric guard is the spray nozzle. It dripped while I was spraying my top. It has to be applied evenly and once it dried I could see circles on my tan top where the drips had dropped. Hopefully they'll faid.I tried to contact 303 but their email bounced. They're located in Australia.
