303 Products Convertible Top Cleaning And Care Kit (30520)

Wow , this is an amazing product, used a couple in the past on well known products, but as you see for yourselves this is absolutely brilliant bit of kit , didn’t know my roof was this green untill I used this product… results are amazing …

My 2001 BMW 325 Ci fabric convertible top was in excellent condition as the car has been garaged for its entire life. However I have never treated the top in any way other than to wash with soap and nylon brush. Both the cleaner and fabric guard appeared to work well. It has since rained (yes it rained in southern California in September) and the water beaded off the top. The top looks gorgeous now, like new. I followed all instructions to the T. I hosed down the top and applied the cleaner with a nylon brush, rinsed it off and reapplied and then rinsed the heck out of it to remove all soap residue. I waited 24 hours for the top to dry in the sun and then in the garage before I applied the fabric guard. The cleaner goes a long way so next time I will only have to buy the fabric guard for a future application as I only have about 1/3 bottle left. I was going to brush on the fabric guard but instead decided to mask the windows and car body and spray it on. I used old sheets and towels and blue painters tape for masking. This worked well and the supplied sprayers worked as expected. I sprayed the fabric guard liberally from front to back and then side to side to be sure I covered the entire top. So far I am very happy with the results and will consider buying some of this companies other products, e.g. speed detailer & graphene detailer.

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.

I have to preface this review by stating that I used the kit just a few days ago, so I am in no position to judge the long term effectiveness.

I decided to try the 303 products after reading a lot of positive reviews here and on other sites as well as going to the company’s web site. So far I have no reason to complain.

I read many reviews which bemoaned the fact that 303 HTFG and other protectants were nearly impossible to use outside due to the effects of even the slightest breeze on the fine mist coming from the sprayer. I had the advantage of applying the HTFG in my garage, so that wasn’t an issue for me.

After cleaning the top with the cleaner and a horse hair brush, I left the top to dry thoroughly in the sun. The top looked pretty good to me, but I’m not sure whether the credit lies with the cleaner or the brush.

I then moved the car into the garage and used a plastic painting drop cloth with an adhesive edge to mask off the rest of the car. I sprayed the HTFG on evenly, but rather liberally. I was a bit worried about overdoing it since during the course of correspondence with a rep from the company I had been cautioned to not over apply. For that reason I decided to forego the suggestion of another reviewer of pouring the HTFG into another container and applying it with a brush. As it turns out, it is okay to do so. The rep later emailed me and confirmed that even the president of company prefers that method for protecting the top on his own car, though not with a fully laden brush. I’m going to try this method in a couple of years or so when I need to reapply, and will tap the brush on the side of the bucket to avoid over saturating the first area that the brush hits. Anyways, once the protectant was on I moved the car back into the drive so that the HTFG could dry and cure properly. The company recommends high temperatures for this part – the hotter the better.

There was enough cleaner for the top on my Audi A4 that I could use it again, but shouldn’t need to as long as the protectant holds out.

As I mentioned above, I haven’t had this protectant on long enough to judge its performance, but I was so impressed with the responsiveness of the company rep to my emailed questions that I am giving 303 HTFG the benefit of the doubt for now. It certainly looks better than when I started.

I will try to update this review in a few months if I can to give a better idea of how well the fabric guard performs. In the mean time I’m going with four stars for ease of use and outstanding customer support.

UPDATE: Who knew they had an edit button?
Well, it’s been nearly two years since I started using this product and I am still very pleased. As long as you follow the instructions it works perfectly! (Clean the top, let it dry, liberally apply the product on a hot day, only rinse the top between treatments – every complaint I read here violated one of those tenets.) I had considered using a brush to apply it, but so far I have stuck to masking the windows and body with the painters’ drop cloths that have the tape on the edge and just spraying.

These products are excellent for cleaning and resealing your convertible roof n your car. Pretty easy to use and after your roof should look new with water heading up and running off the roof. The trick is to thoroughly wet your roof before applying cleaner then rinsing completely until no suds. Let roof dry before applying fabric sealer then let cure for 4-6 hours after application. A bit time consuming but thoroughly worth it for the results. Recommended.
