Packasport carriers are the best quality box on the market. However, since they are handcrafted in fiberglass, they need to be finished with a gel-coat. Though beautiful, they are susceptible to fading in the sun. That’s why we recommend to use a good quality wax 1-2 time a year.
We suggest using a high quality car wax to bring back the shine. According to Darren Priest of a blog called “Best Auto Detailing tips”:
Mothers Wax is a good retail product that we sugguest.
Pinnacle is offers a professional grade product that we like at Packasport.
Otherwise, you could get it repainted at a local auto-body shop with automotive paint that is less likely to fade. Perhaps choose a different color than black for some fun. I have a bright blue box and it’s great for finding it in a parking lot.
