Marchetti SF260 - Fuselage Build
Hi, I'm looking for any suggestions on the next best steps to take on this fuselage. I have assembled and planked, and sanded with 60, 80, and 220 grit sand paper. The instructions for this imported model suggest painting the fuselage with white glue, then sanding. Hopefully I didn't shoot myself in the foot, but I had glued it so well planking it, I felt it would be easier to rough sand the entire fuselage before painting it with glue. Is it necessary to paint it with glue since I plan to cover it with glass?
My plan from this point is to:
Fill surface imperfections with Hobbico Wood filler.
Sand with 220.
Fill again and sand with 320.
Fill again and sand with 400.
Cover fuseleage with 1/2 oz fiberglass and resin.
Sand with 100.
Glazing Spot Putty, Solvant based Bondo brand to fill imperfections
Use 80 grit no load paper to sand
Then 180 grit
Then 320 grit
Use Isopropyl Alcohol to wipe down and remove dust with paper towel
Spray can scratch filler and primer (MotoMaster) light coats only
Use body putty again to fill any remaining blemishes
Wet sand the primed and filled surface at this point (just get sand paper wet in bucket of water and sand…continue to use 320 grit paper. Then do another coat of primer, dry and wet sand with 400 grit paper
Repeat steps for perfection, then spray primer one last time, and do light surface rub with 600 grit paper, and ready to paint!
Still new to this, but any suggestions would be greatly appreciated.

I see no reason to paint the surface with glue.
Instead of that expensive Hobbico filler, I use light weight spackle from the Hardware store.
220 grit sand paper should be enough, when glassing. No need to go with a finer grit.
After glassing, your finishing techniques appear to be sound.
You've done a great job on the fuselage. Keep up the good work !!!

RE: Marchetti SF260 - Fuselage Build
Thank you. I'm just trying my best to get a perfect finish for the first time. Normally, I rush to finish projects like this, but I really want this one to turn out as best as possible. I am going to paint a two-tone camo theme to match the one I flew with Air-combat USA. I spent about 20 hours researching on the internet to find an SF260 RC plane, and had to import the model from Italy. I'll probably just hang it from the ceiling when I'm done, and eventually, after taking tons of pictures, risk flying it. I attached examples of the completed plane, and the real one that I want to duplicate in my RC.

A friend of mine had a similar experience, and was going to build the model, too. Instead, he built a full scale home built Kitfox.
Another friend has has plans for this model, but hasn't started construction.
Have fun with your project !!!

Wish I had the budget for that. I looked up Kitfox Planes and they look pretty nice.
If the Marchetti kit I build turns out nice, I might build one from scratch. I still have a lot to learn. Like fiberglassing. I've watched a youtube video on it, but haven't ever tried it for real. I'm going to waste some test material on something else before I try my plane. The video I watched made Fiberglassing look realtively easy, just time consuming. Is it easy to overlap pieces of fiberglass?

When glassing, I use .58 oz cloth. It's very easy to work with. Instead of resin, or epoxy, I use MinnWax PollyCryllic. It's a waterbased product.
Seams are not a problem, as they are usually covered with with whatever product used, and blended in.
I lay down 2 coats of the Poly, and fill the weave with automotive primer sealer to fill the weave, sanding between coats.
Getting a good finish isn't hard, but it is time consuming.
