Hi, Sorry I missed this one. Gunboat was using Awlgrip and Alexseal... my guess is probably for the Alexseal during that time. If it is really important to you to get the right reference I can do some asking around (I was not involved at that time). But to be honest, all of the paints you mention will be compatible with one another. Get a professional to do an assessment for you on adhesion, what is surveyed will tell you how much of the old stuff you should take off.Does anyone know what kind of paint Gunboat was using on the 48s? Getting ready to give 4806 some needed love and don't want to do more damage than good.
Awlgrip, Awlcraft, Imron, PPG Concept, Alexseal.... so many options each with there own caveats on compounding/polishing/waxing etc...
