We coated ours about 6 months ago and have towed it about 4000 miles. I have not seen any discoloration that I notice.
I have noticed that the top leading edges, at the roof line, there has been some spots of Red Max that came off. I don't know if this is due to not fully removing the wax that was under the Red Max. It is clear that the trailer needs to be really clean before application and I know next time I'll do a better job.
Our trailer is now 21 years old and people always think it's brand new (we've given about 40 tours since we left NH). Even other Scamp
owners think so. It provides a great looking finish.
I will say I probably would have waxed the Scamp
2 or 3 times by now without REd Max. Now I just wait for morning condensation and wipe it down.
