New to me boat!

[Broke Down]

My brother-in-law has been watching me work on my little Alumacraft and I think he's been feeling sorry for me. I get a text to call him and he tells me about this 2003 Sea Fox 195 his customer wants to sell. I show up and look at it because the engine had a mild fire and has some blisters on the foot and a small portion of the gel coat. It has a Mercury 115 hp four stroke. Long story short, I bought it for a really good deal today. I need to paint a few things on the engine and get some gel coat repaired. Any suggestions on paint repair on the engine? Rattle can is cheap but I don't want it to peel.
