Today went better, no drips. Cutting down the air volume helped. I also thinned the primer paint only 8:1. Other users thin more but their equipment is different. The Fugi Q4 instructions say to make the airflow the last adjustment after thinning, fan size and paint volume. But cutting back on the airflow makes the other adjustments easier for the small surfaces in the cockpit. It is important to slow down and work with the gun until you get the pattern you need. Currently I'm putting more practice paint on the tape and paper than I put on the work. I also learned to take off the mask and leave for a while after each coat.

I finished spraying the cockpit area with primer. I couldn't get the top coat on. My practice panels were off. Too much orange peel. Also the gun started thowing out stuff like spider webs. I go with a thinner mixture and practice some more. The paint works well brushed on. It lays down very smooth. I may consider brush painting the main decks. It is something I could do at the Marina after I get in the water.

Yeah stick with it. For me its more like pray spaint then spray paint :)

I stopped by and showed the pro my last practice panel. He gave me some tips on how to improve things. He also wanted me to consider using a 2 part polyester finishing finishing putty to fill all the pinholes and spiderwebs cracks on the outside decks. He took most of the original topcoat off the flybridge and Cowl and I had to pay for all that. So I consulted a guy at the autoparts store and got some Evercoat 100421 Easy Sand. $32 for 30 ounces. It says it contains ZNX-7 for adhesion to metal including aluminum. This stuff is applied with a plastic spreader in thin layers to build up for sanding. It is sandable in 20 minutes. It says not to apply it over fresh or uncured coatings. I'll stick with the water tite around stanchion bases and other areas with screw holes. I still got to call or go on-line to find when it is fully cured and if it is ok uncovered outdoors.

After a day of practice on pieces of junk aluminum and foil taped to plywood I proceeded to paint the top deck and cabin sides with primer. I was all wrong with my thicker mixes for the Schilling paint. The Fugi Q4 turbine system is adjustable enough to throw out 8:1, 6:1, 3:1 whatever you want. The trick is to find a good mix that is easy to make a wet or a fog coat at various fan sizes and that won't run or show to much peel. You need to learn to vary fan, fluid or air adjustment on the fly. I settled on 20 DIN which I got by starting with 4:1 which was 26 DIN and then adding more thinner.

Things were going very well with the spraying until the end of the day. I ran out of 20 DIN paint before I finished the hood over the windshield. It was getting dark and I was bone tired from all the taping and finishing the tent cover I had to build over the boat. I should have gone home and picked it up the next day. Instead I grabbed a bottle of 14 DIN I was testing and put it in the gun. It seemed to work very well flattening out nicely. Then I ran around the cabin touching up thin spots. Well there was a dusting of granular paint all over my previous work on the roof area. I didn't crank back the air and didn't spot that I was putting out a huge amount of overspray with the thinner paint. Some of it is loose and will wipe off. Some is stuck and will have to be sanded. Too bad because the unsanded primer has just the right amount of bite to hold the top coat. Then I topped off the day by dropping one my small spray gun paint containers under the gas tank where it will never be recovered.

The more I work with the Fugi gun the better I like it. It can throw out a 10"-12" fan size or make a dime size round pattern. I am going to try the bigger fan size on the roof over the kitchen area.

P.S. Since then I just mix the primer and top coat 3:1 with thinner. This yields 17-18 DIN. Thinner paint is OK on horizontal surfaces but starts to sag or run on vertical surfaces.

Schilling doesn't think the rubber enamel can be rolled because of the bubbles. I bought some Penetrol which is supposed to help paint flow out and keep a wet edge. I rolled some with 10% penetrol out on a test panel and tipped out the bubbles. Seemed OK but it still dries very fast so I need to do some more tests. I used a brush under the windshield hood and the lower part of the cabin side near the deck. Results were mixed. I got good single coat coverage but with some brush marks. Used 10% Penetrol. I may roll or brush the decks. Be nice to get away from all the covering and taping you need to do to spray.

Here is an update on my painting project. I talked to a auto paint expert to get some info on how to buff out my finish coat. He said that he already sold me 3M 3000 compound and 1500/2000 sandpaper to shine up my plexiglass windscreen. That should work fine for the Schilling enamel. I hope he is right. As we were talking I mentioned that everyone including him was recommending several thin coats. But my Fugi Q4 turbine seemed to work best with a couple of medium coats. The thin coats were too dry. He said that that I neglected to tell him I was using a turbine gun. Turbine and compressor guns work differently and some turbine just need to shoot thicker coats so do what works. I did buy a 1 mm nozzle to try out but I can probably finish with the 1.4 mm.

My turbine is fairly quiet and easy to carry around and set up. It would have been easier for me to have started with a high quality gravity feed compressor gun. Now that the learning curve is over the turbine should work OK for me.

I have to put the top coat on the deck and sides over the dinette/kitchen area then the cabin area will be done. After that I will mount the professionally painted cowls and flybridge and launch the boat. The deck and hull can wait.

Working outside was a big mistake. I should have tried harder to find and rent a big workshop. I had to build a shelter over the boat before I could even start. At least the boat is close.

I chose the Schilling paint because it is supposed to bond well with the original factory paint on my 32'. I have a 28' to paint after the 32' is done. It has multiple coats of who knows what on it. I will choose paint that I can get locally. I have to travel to Cleveland to get more of the Schilling enamel. I also want a system that includes a high build primer. Putting down finishing or smoothing putty works well but just takes too long.

DiverDennis and others have posted a lot of painting information which I will study further. Here are some requirements for my next system. A etchant or spot primer that won't lift whatever old paint I decide to leave on. It's Ok to sand to smooth out the final primer coat or prior to buffing the final top coat. But, no sanding between sprayed on primer or top coats. I want to be able to roll, brush or spray the top coats. Nothing too complex..I don't want a massive paint failure because I misunderstood some fine print. Auto guys can use a hardener additive which fully cures the paint in hours rather than weeks. I would like this feature. I noticed that there is evidence of soft uncured original paint under the rain gutter and other hull attachments.

Jeff,

Thanks for the tips. I got plenty of boat to try your system on. Makes sense to use a heavier paper since I have a couple of sags and thick spots to cut down. The compound I have is 3M Perfect-IT 3000. It says on the bottle it will take out 1500 and finer sanding scratches. If it is the same stuff you use it should also work on the coarser paper.

When I did my plexiglass windscreen I didn't know what I was doing. I did have some scratches from the 1500 that were hard to remove and seemed to be to deep for the 1500. Your technique calls for a lot of clean water while wet sanding. I just wet the surface. Then I probably gooped on too much compound. I noticed that the buffer will start to glide real easy as the compound dries. Good thing about 1/4 plexiglass is that you get all the do-overs you need. Not so with paint right?

The bottle says to use enough compound on the paint for a thin wet film for one or two passes before it start to dry. That means not much? Then it says to use light to medium pressure reducing pressure as the compound begins to dry. The instructions also say to "Spur pad as necessary to assist cleanup". I have no idea what that means. Also what kind of buffing pad do I use? I have thin cotton ones and big fluffy wooly ones?
