Follow Up: Hydrosilex Recharge & Marine – Do They Live up to the Hype?


I had debated the need for this post as I haven’t seen much marketing by Hydrosilex recently, but given how quickly the product gained popularity when it was first released, it seems a follow-up may be beneficial for anyone still considering purchasing one of their spray on protection options.  About 2 years ago my initial review articles were published for both Hydrosilex Recharge (here) and Hydrosilex Marine (here).  The products are similar in that they both claim to be durable, easy to apply, SiO2-based spray-on “coatings”.  The main difference seems to be in their claimed durability of up to 6-months for Recharge and 1 year for Marine.  The manufacturer’s bold claims had me skeptical from the getgo, so some real-world testing was certainly in order.

My vehicles are exposed to all weather and far more than the average amount of miles which makes them great test subjects.  In this specific instance, I wanted to compare the allegedly super durable Hydrosilex products to something that a lot of us are familiar with – Meguiar’s D156 Synthetic Xpress Spray Wax.  D156 has been a staple in my garage for years.  Like Hydrosilex, D156 is also effortless to use and produce great initial results, but at an enormously lower cost.  D156 currently costs $0.25 per ounce (1-gallon size) while Hydrosilex Recharge and Marine are currently listed for $1.56 (1-gallon size) and $2.22 (32 oz. size) per ounce, respectively.  For such a tremendous cost increase, I was going to be pretty demanding when analyzing the performance of the Hydrosilex products.  I have no issue with paying a premium when the results reflect the price, so I was hoping there would be a justification for the cost.

For my test, I thoroughly washed and prepared the passenger front door panel using the Hydrosilex Rewind prep solution.  An even application of each product was then applied in 3 sections marked off by the masking tape.

After a couple of weeks of driving, the panel had accumulated a normal amount of dirt and grime.  This test was performed in November which, in the Midwest, means freezing temperatures, salt solution, and other chemicals on the roadways,

The initial rinse revealed a complete lack of hydrophobic behavior over the majority of the door.  This was not unexpected given the amount of film that had likely built up on the surface during normal use, but I was hopeful the claimed protection would allow the film to easily wash away and reveal tight beading and rapid sheeting once clean.

The panel was soaked with foam then hand washed.

Upon rinsing, there was no major revival to the water behavior.  Water slowly sheeted from the lower half of the panel with zero beading.  I rewashed the panel again to verify that it was clean, and still, no changes to report.

Ultimately the lack of beading/sheeting is not a true indication of whether or not a protective layer still might exist, but it is a property that many consumers expect to witness for a longer period than 2 weeks when a product is claiming many months of life.  So, using water behavior as the sole means of analysis, the Hydrosilex products seem to perform no better than a spray-on synthetic wax that has been around for many years and costs many times less.  I had continued to experiment with Hydrosilex as a quick detailer and drying aid.  The product was certainly a breeze to use, but at the end of the day, I would not purchase it again.  There are so many products that perform as well, and many that perform much better, at a much lower cost.  Like I said earlier, I am willing to pay a premium if the results reflect the price, but with Hydrosilex I did not feel that was the case.

    Hi Zach, good to see you posting again. My review of Hydrosilex Recharge was the same, not worth the price. Many new products get hyped early in their release, Mothers CMX is just one that comes to mind, that after we Detailers get our hands on the product they fail dramatically. I know of few products that live up to manufacturers claims, and that is sad. Simply manufacturers are going after short term gains only to lose market share in the future. After I get burned by a manufacturers product I don’t buy Anything in their line again. I hope other Detailers start boycotting manufacturers that lie about their products. If we stop buying from manufacturers that flat out lie, and offer no refund, many problem products from companies like Hydrosilex and Mothers (and many more) companies will think twice before making outlandish claims of durability (maybe). We detailers are always searching for the Holy Grail of products, the one that shines the best, ease of application, and lasts forever and that opens us to charlatans offering just that only to fool us once again. We need to be better and that will force manufacturers to be better.

    I read your review with great interest. I had my cars ceramic coated by a CeramicPro dealer. i was looking for a simple wipe-on wipe-off product and he recommended Hydrosilex Recharge. I really like the enhanced gloss look and ease of use. My experience is similar to your experience, and I was hoping for 1-2 months endurance.
    I really like the CarPro line of products for washing and some of their other products. I tried both Reload 2.0 and Elixer. My experience with both of those products did not go well due to the fussiness of application; and the Reload created removal issues when I returned for my annual coating maintenance.
    All this begs the question…which product should I use as a maintenance spray sealant? I’m reluctant to try CarPro Hydr02 Lite due to problems with the other two products. Your recommendations would be greatly appreciated.

      Hi, I’ve always liked Relaod for a maintenance product, i get about the same as you 1-2 months protection, but you may want to talk to your coating installer. Not all products play well together and they may be able to put you on the correct path. Personally I do not like Hydr02Lyte or Hydrosilex Recharge. With Hydr0 i just didnt like the spray on then spray activation application and with Recharge I only got a week or so of protection. My current go to topper is IGL Premier, it costs somewhat more, but I get almost 6 months of beading before reapplication is needed, so in the long run it costs less.
