My thinking is if it is good enough for marine use it should be good for our fiberglass trailers.
In fact, I'm treating my
Scamp as if it is an ocean going vessel. Up here in Washington state it is damp most of the year. Every original steel fastener that I have had to cut off is getting replaced with stainless steel. All new fasteners will be stainless as well.
I am also going to install marine stainless steel cabin LED dome
lights under my cabinets.
I am always looking for something to use from the marine or pleasure boat industry on my trailer. They have some neat stuff that I'm sure will stand up to extreme weather conditions.
