I’m getting ready to repaint my 2004 Tahoe fiberglass boat while I have it out of the water. The gelcoat is faded and has a few small blemishes, so I want to clean it up and give it a fresh, durable finish.

My basic plan:

• Wash and degrease the hull thoroughly

• Sand everything smooth

• Repair any chips or cracks

• Wipe down with solvent

• Mask all hardware and the waterline

• Apply marine-grade primer

• Apply multiple thin coats of polyurethane or gelcoat

• Let everything cure fully before launching

What I need advice on:

• Best primer and paint/gelcoat brands you recommend

• Whether polyurethane or gelcoat gives better long-term results

• Rolling/brushing vs spraying for a home setup

• Any common pitfalls to avoid, especially with prep or curing

Any tips, product suggestions, or photos of similar projects would really help. Thanks in advance.
