Hi Lou, Ive had great luck with the stuff I bought from you when I painted the bare grumman 19 square stern. Cleaned scuffed sanded primed and painted ,came out great. Havent felt the need to touch it up, it just does not need it. This is a new boat that I got a great deal on ,bad color(powder blue) and someone on a boat forum suggested if you are going to paint it why not use a gel coat. I dont know anything about it. I know I can paint a duck boat but gel coat, who knows. When I pm'ed you the other day I really am leaning just painting it. Like I said before it fiberglass . Should I prime then paint or use a all in one primer/paint. Im actually picking the boat up kinda near you. Bob

Where abouts around here are you picking it up? Coffee's always on.
Unless you've done a bunch of re-gelling, you'll probably not be happy with the results. It's finicky stuff and not easy to get looking good. It looks so good on a new boat because it's shot into the mold onto a smooth surface and laminated over.
Thinning is required (lots of it) in order to get it to spray out of a regular spray gun properly and the thinner is also needed to give you a duller finish.
You're call but...I'd highly recommend a paint job. Scuff the gel coat and paint it. IMHO.
Holler with any questions and let me know how it goes for you.

Around here (Newport RI) the fancy sailboat guys have boats sprayed with Imron when they want to renew dull gelcoat but I agree about paint for a different reason. Fiberglas needs to be protected from the sun & paint does a great job.
Imron is tough though. I had some truck tires sandblasted years ago & the sandblast guy told me that if they were imroned I could not expect him to get them to bare metal.

Gary,
Why were you having the tires sandblasted? More importantly, why would you want them down to the bare metal? Isn't there supposed to be a rubber covering (usually referred to as tread) over the metal belting? :>) :>) :>)
( sorry couldn't resist)

I think you are mistaken.....were they not old style tractor wheels of solid metal with spikes?

Matt,
Why is it I am mistaken? You are the only one to mention wheels.

Joking with the rubber tire thingy --- no offense I hope
Matt,
I was not offended but your reply was directed to me, so I took that to refer to what I wrote.

Be really careful with Imron or other brand 2 part eurathane enamels. They are really toxic. The MSDS sheets call out full body suits and outside air supply respirators. Having said that they are the most durable paints on the market and you can get flattening additives to give you a dull finish.
Have you considered metal flake
)) That would definitely make a fashion statement.

Re: 2 part paints
I agree on toxicity. But spraying puts more material in the air than brushing or rolling. A brush/roll on Imron job, with flatteners in the material in your driveway is not going to be as dangerous as spraying in an unventilated space.
For a spray on finish you could go to a body shop & get pricing for them to shoot w/Imron. I did this once for a winch bumper. Body shops have all the right safety equipment.

I agree. I believe Interlux has a brushable version but I don't remember if they have the flatening additive. Imron is a Dupont brand. There are a number if cmpanies who make 2 part eurathane paints.
