Hi,
I have Awlgrip on my hull. Here's my take on it. The AllCare and AllWash products work well to maintain your finish, and if used seasonly/more, you will preserve the shine. The shine with Awlgrip is on the surface, and if you buff it with compounds, you will loose it, and even if it looks good on the short term, it will not last. My hull was done with Awlgrip about 9 years ago, and it has maintained its shine. I, and the prior owner, were/are religious in using the AwlWash and Allcare products from the start, and they have paid off. If your Awlgrip finish is faded, you can try to buff it, but the results will probably not be lasting since the shine is in the very top surface. Hope this helps.
