I had to tie on a concrete wall in high wind
conditions (long story, I had no other choice). I had plenty of fenders on, but there was a lot of grinding of the fenders, and now I am left with several black marks on the gelcoat
(see picture attached). I can feel that at least in a couple of places, the fenders actually ground into the gelcoat
. Still quite superficial, but it is there...
I have three areas like this (this one is the worst though), corresponding to three fenders
Somebody at the marina told me that it may likely be resolved just by buffing the gelcoat.
I have no previous experience with gelcoat buffing (I have some limited experience with structural fiberglass
repairs/strengthening, but never in visible areas). I watched a couple of videos on YouTube, but I am still very hesitant on how this should be done.
Can the gelcoat experts in this forum help by answering the following questions?
- What is the best compound for this kind of job? I understand there are different compounds with different characteristics.
- What are the steps to prepare for buffing? Just cleaning
and de-waxing the area, or do I need to sand as well? Do I isolate the area with mask tape or you are supposed to buff a much larger area?
- Better done by hand or by power tool? (I actually have access to a buffer, but I have never used it). The area is not that large, can be handle by hand if that is the easier way...
- Other tips/suggestion
