Of course you knew I would show up on this post. We have such similar experiences with SharkHyde, timing and vintage of trailer. But there might be two big differences.
I am actually going the other way. I have spent a ton of time compounding/polishing my 1986 trailer and I am just so happy that something stops the never ending oxidation. For the first three years I have owned my girl I haven't been able to keep up with re-polishing and so I couldn't get to the new polishing. I have my trailer 1/2 way stripped with an initial compounding and 1/4 stripped/compounded/polished and finished with SharkHyde. Until I applied SharkHyde, I just couldn't keep up. The first difference
is my trailer has a hidden secret. FILAFORM OXIDATION! Tiny worm like strips of oxidation all over the skin. It can take 10 passes of the compound and even sandpaper (be very careful on your research here) just to clear the oxidation. The SharkHyde seems to stop the oxidation from spreading.
The second difference
is I really don't care about the shine
I just want a clean consistent finish. In fact in a perfrect world (that includes me with a lot of money), I would have P&S re-finish my trailer. I have seen some pictures of their projects and they do incredible work. A trailer coming out of their shop looks as good as it did from the factory. SharkHyde is a substitute until I can collect the $5,000+ for a high-quality professional clear-coat application. It works really well in that capacity.
With all that said, I want to hear as much about taking it off from you as I did when you put it on. So please continue your post.
