It is amazing what a good buffer, a lot of elbow grease and a few days of time can do to gelcoat.

Many owners jump to painting rather than detailing the hull. I was shocked when i did both of my boats, they looked totally different.

Is the gelcoat chalky? White residue on your finger after running it over the gelcoat?

Is it just dull and not shiny?

Note, a good variable speed buffer is recommended. Not too large (10") or too small (4"). I prefer Porter Cable or Makita tools myself.

If chalky, one would start by either wet sanding or using a heavy duty fiberglass compound. 3M, Starbright, Meguiers are several decent brands.

IF not chalky but dull, start with a medium duty compound. One good product is Meguirers #44

I would follow that with 3M's Finesse-It II finishing product.

A good marine wax will protect your work.

I suggest watching some videos on Youtube on technique before you start. IF a novice, it saves lots of mistakes and aggravation.
