Optimum Opti-Bond vs CarPro PERL

Recommended Posts

For the last 2 weeks I've been trialing a test of Optimum's Opti-Bond vs CarPro PERL.

This was very subjective, and hopefully honest test. Spoiler alert - I will start out by saying both products are fantastic and are more than worthy of purchasing.
I didn't get any great photos as it was too hard to tell the subtle differences between them so you will have to take my word for it. Both products are water based
and can be diluted if needed/desired.

Optimum Opti-Bond

+ Leaves a perfectly smooth high gloss finish with no greasy residue
+ Can be diluted further to reduce gloss (I wouldn't go past 1:1 as the consistency gets... weird)
+ Very good value for money (as usual with Optimum)
+ Although not really obvious, can be used on external (and even internal) plastic trim and rubber
+ Still going strong after 2 weeks in a daily driven car in a variety of weather
+ Does not appear blotchy or streaky if applied unevenly

- The smell is hard to describe, but it's not great
- Has trouble bonding to older rubber that has started to dry
- The high gloss look may not be desirable for some


Applied undiluted to the tyre.




+ Produces a fantastic satin finish on everything it touches
+ Has some kind of darkening effect built in that makes rubber look new
+ Smells amazing!
+ Can be diluted down for use on leather and plastic if needed
+ Very good value for money when purchased in the 1 litre size

- Produced an unsightly cheap silicone look in direct sunlight when used at full strength (on tyres at least)
- If you are after a high gloss, wet look, this may not be the best choice
- Durability on tyres is only average. Starting to noticabley drop off after 2 weeks
- Due to the darkening effect, it can appear 'patchy' if you don't apply it evenly


Applied undiluted to the tyre.



Both products perform great once you get the hang of the quirks each have. For instance - PERL will leave a streaky finish if not wiped down soon after applying and Opti-Bond turns into a really weird consistency if you dilute it too much. I will say that a huge downside to PERL is when applied at full strength to tyres it has a horrible cheap silicone dressing look to it when hit by full sunlight. I took my car to a friends house to actually show it off after washing it on the weekend and this actually made me embarrassed  when he saw it.

I would happily choose and love using either product, but if I had to go with only one I would give the very slightest advantage to Opti-Bond. I think the name should be changed to Opti-Bond External Trim and Tire Gel as in my experience it actually outperformed PERL on external plastic. I applied it to my mothers car which had very faded external plastic trim, and upon seeing the car weeks later it was still performing well even though it sits outside 24/7.

If you have any experiences with either of these products please let me know!
