On July 19th I started this thread by describing the small stains in the gel coat on one side of our rig.
Yesterday I finally removed the stains and am happy to report that the job was almost too easy to believe. The gel coat in question is now as white and shiny as it was three years ago.
I’d purchased two types of Fiberglass Stain Remover, but didn’t start work until yesterday for fear that the job would be too time consuming to fit in with other commitments.
The bottom line is that both of the products worked, but
Starbrite Ultimate was much easier to use than the FSR.
In case you’re interested in the details, here is a summary of the work:
I first started with Davis FSR because it is a thick gel that could be used without fear of it spreading too rapidly to control.
I applied some gel with a small kitchen sponge to a 12” square area, rubbing it into the surface, letting it sit for a few minutes, and then wiping the area with a clean wet towel. This removed some of the stain. I repeated this on the same area and the stain was gone.
After using the above procedure with the same results on two other 12" square areas, I decided to try the other remover—Starbrite Ultimate. The product label says it is also a gel, but it is much more fluid and comes in a spray bottle.
I first used the product on an area that included a small amount of decal and painted surface. There was no resulting damage and the gel coat was as white as the previous sections after just this one try.
I immediately recognized that this process could move much faster, so I continued spraying and wiping on areas of about twenty square feet until the entire side of the coach was clean. This required about the same amount of effort as hand washing the coach.
The rear cap had been developing some stains for unknown reasons over the last six months that I wasn’t able to remove in the past. There is also some “yellowing” there. Since the Starbrite label states that the product will remove yellowing, I applied this product to the rear cap and it now looks almost new. The yellowing is not completely gone, but perhaps a few more applications will help that too.
That’s all for now.
