I have never used GIBBS before.
Don't know if it works, or if it doesn't.
But that is the point of these forums; to share our experiences and make suggestions as best we can.
I think both taoworm23 and pleofixation make some very good points.
Taoworm23 is right. The whole point is to seal the skin to help prevent wear and to keep the rubber/latex skin soft and supple. If it dries out it will crack. Baby powder is a desiccant and does dry out skin. But baby powder was also the recommendation from the manufacturer, it was not just someone else's suggestion. Of course, pleo's skin isn't moist or hydrated. Water is not the issue. In fact, GIBBS drives out the moisture. That's one of it's jobs! But latex and rubber don't need water to stay supple, they need oils, which is what GIBBS provides. So, logically, a product like GIBBS is ideally what you want to use.
But on the other hand, GIBBS does have a lot of really volatile compounds in it, any number of which might just as well eat away at the rubber skin. And as pleofixation said, there are a lot of hazardous chemicals involved that are not meant to be handled constantly. If you have small children playing with your pleo, you should consider that before using a product like GIBBS.
As to how well it works, I don't know. Out of 120,000 pleo sold, so far we only know of two people who have used GIBBS. One loves it, one said it doesn't do any good. Sounds to me like we don't have enough experience for a good answer one way or the other.
I would actually like to encourage more open discussion like this. And ask that people don't take things too personal. It is through these discussions that we all can learn and benefit. And sometimes things can get a little heated, as some people can be a little passionate about their views. Disagreement is good, as long as we stay away from personal attacks and accusations. Most things are not cut-and-dried, so we benefit from opposing viewpoints.
I would like to encourage pleofixation and taoworm23 to share more of their experiences with their pleos. I wish I knew more about each situation so as to better understand the pros and cons. Because even though fancyfont may be right, I'd rather not have to earn to love our pleos without paint.
