[sprink56]

Here are a few pics showing the beginnings of this project. You can see the difference between the buffed areas and the chalked gel coat.

I will update as we progress.

I am curious to know what products and application method you will be using.

I think I'm going to have to build an xl spread sheet on this one...:thumbsup:

Step 1. Wash Boat thoroughly

Step 2. Wet sand with DA 800 grit on smooth surfaces/1000 grit on non-skid.

Step 3 Compound all surfaces with 3M Super Duty Extra Heavy Compound.

Step 4. Compound all surfaces with 3M Extra Cut.

Step 5. Apply 3M Scotchgard™ Marine Liquid Wax, 09061

Step 6. Polish all metal window frames, bow rails, etc. with Flitz.

Step 7. Wash entire boat and canvas, dry down and clean/treat all Stratta Glass with IMAR 210 Cleaner and Scratch remover.

We are 2/3 of the way around the hull with Steps 1~5. The top side is thru Step No. 4.

Here are some progress photos. I am very pleased with the results so far. We will finish tomorrow.

Dang with that much chalk any shine looks better! Looks good now though! That is alot of work especially on a tank like the 390. I get away with just the Extra Cut Compound and wax over that. I'm always amazed by the results.
Keeping them looking like that is the tough part!
Good work man!

She's done. we just turned back the clock 20 years on this boat. I am very pleased with the results. Here are 2 pics...tough to see any shine on white in this light...I'll get some better shots tomorrow. :thumbsup:

Looks great, John.
They laid the gelcoat on pretty thick "back in the day" and with enough compound can be brought back to near new condition.

What are those "things" forward of the windshield on each side- speakers??

Thanks....yep, speakers held on with a super duper velcro strip! (By PO)

One minor detail I'm still working is the port lights for the master state room. Trying to get them clear with Meguires No. 10 plastic polish without result. Any Ideas.:huh:

Your boat looks great. You might try Semicrome metal polish on the port lights. I used some on the plastic speedometer lense of my 66 nova. It was scuffed and had some overspray on it. It still looks great after about 5+ years. I only rubbed back and forth and not in circles. You can by it at motorcycle shops.

Thanks for the compliment and the suggestion...I'll give it a try.

Thought just came to mind. Maybe a 3m headlight lense refinishing/ restorer kit might work? I could get you a part number if needed. Good luck.

I didn't know you were actually supposed to be able to see out of those portlights

To even make the 39 stand out more. Take off the plastic side vents and painted them. You can get a color match by getting a paint color chart from a body shop paint supply store to match the boat gell coat to the paint. Then have them mix it in a spray can to paint the vents. Tell the paint supply shop that you are spraying plastic and they will put a flex additive in the paint. The vents will then match the rest of the boat and last for years.
I wet sanded my 39 with an air DA Wet sander it took alot less time. My hats off to you as for hand sanding the boat.
