The decision to recoat is driven by several factors. I'm not sure what is driving your decision but here is my list:
- Product failure (or lack of noticeable benefits)
- An undesirable level of "love marks" (wash swirls and other handling marks)
- Damage to a panel which needs to be redone
- ....or simply because you want to try something else
Since being introduced to paint coatings (regardless if it is SiO2 or SiC based), I've had the opportunity to try many and can say honestly that PBL and DP coating (and not GC) are the easiest coating to apply. Out of these, the most number of coatings I performed was with the PBL line. The results were all initially pretty great however I found myself less and less satisfied with the results over time, and eventually opted to replace it. A few of my customer experienced the same and requested a recoat. Some "failed" earlier than other. Please note that I put the word failed in quotes because in some case the coating had not truly failed but the properties were so poor that nothing could revive them. In some cases a good chemical decontamination with Reset and IronX revived the properties, but in others nothing was found to "revive" them, so if was decided that a recoat was in order. The earliest true failure I've seen with the above quoted product (meaning it could not be revived) was 6 months however have had a few that lasted beyond the year mark.
I cannot speak of the properties of CG because I've just recently had my first experience with it (
Click here for my review ), but the other 2 are very similar in technologies and results that I can speak of interchangeable results. The initial gloss enhancement of PBL/DP was great but faded quickly. There is no real scratch resistance (compared to other products) and the hydrophobic cues become progressively less starting around 4 months. The PBL line does have a booster which I have used however the "gains" were very temporary. This was expected because the booster did not have the "perfect" substrate. On my truck, the coating was replaced before 9 months and was replaced with CQuartz. PBL is MUCH easier to apply than CQuartz however the lasting benifits (gloss/look/function) goes to CQuartz. Handling marks are also less noticeable with CQuartz but without having a standardize controlled test what I am providing is purely anecdotal.
If the PBL line had better LASTING properties I think the ease of application would make it a serious contender, however the balance does favor CQuartz even with its application which is definitely not as easy as "spritz and spread"
I hope that helps
