Status: offline 		This is the BM V3 I am Monokoting. What I need is a lot of input on jointing the monokote to the cowl. I am afraid to sand much more for fear of going threw. I will be using Lustrekote Missile Red. What color should I use as a base or primmer coat, an can one of these clear coats work. If my memory serves me when I esed the clear coat it shined so much it would blind you, but when it dry ed it smoked up.How about some help with this beauty

Status: offline 		hi Wendell, looks good so far!

Paint the cowl. use a light grey primer first, be sure to get the pinholes filled. What I do is use BVM pinhole filler first, then spray primer. Usually a quick sand with 400-600 grit and it's ready for paint right there.

Don't get too crazy with sanding and filling around that cowl on a monokoted plane. you will have a seam there unless your name is Faye Stilley LOL

After the paint fully cures, just overlap the monokote about 1/4" onto the cowl, taking care to match up the colors. Done. use graphics to camaflouge the seam. Only thing I know how to do.

I'm redoing the prototype as I type this, and will have it in Birmingham at the contest this weekend if you want to drive down and have a look. I'm not too worried how this one looks, this plane is a used up $2 **** but she still flies SWEET. So assuming I can get it test flown and trimmed out, I'm flying this weekend ice cold with no practice (can you say "sitting duck"?) So my goal is no zeroes for at least one round. After that....GAME ON!!!

Status: offline 		HI All,

I've got the electric twins in white k-36 primer.

I tried something new, I mixed in 1 part DCC white with 2 parts k-36 - reduced that to 50% with DT870 and shot a nice thin coat. It not a pur white but it is a couple shades whiter than the straight k-36. I am sanding this out to 400 dry right now (5:30am) and will shoot another overreduced coat of k-36/white dcc this time mixed 1 : 1.

looking great so far and I think this mixture with the DCC tint is the wa to go and it's should be much lighter in weight than straight k-36 - plus so far it seems to sand and fill just like the k-36.

I also found two new (to me ) products at my paint store that should be helpful. One is this spary can of PPG Adhesive remover - should be great for cleanup after using spary masks. and the other is this scuffing paste to be used with the grey superfine sctochbrite pads. The paint scheme on these electrics requires the white base to be overpainted with trim colors, I am hoping this scuffing paste will speed the job....



back to sanding

Status: offline 		okay after the first hour sanding the k-36/DCC white base - I am really impressed that the addition of the white DCC even improves the sandability of the k-36, seems to fill pin holes better and is a slightly harder coat, but that makes it even better smoother base - sanding with 320 and 400 grit dry.

one of the fuses is almost completed in about an hour - it's going to take at least 2 full hours to sand out to 400 for each plane -

Status: offline 		Just a question. Can the final clear coat of DCC be rubbed out? Mine came out looking slick and wet but since I painted half in my garage and half in I got a few dust spots on it. I'd like to do something with it but I don't want to risk screwing it up. Thanks, Mike

Status: offline 		Oh absolutely Mike! I'm betting dean will detail the process, but it starts with wet sanding, compounding and polishing, and is considered a necessary step for a class AAA finish.

Although sometimes you just get lucky with the clear, if you take the time to do this, it gets that really soaking wet shine.

Status: offline 		HI Mike,

Yes you can do that, DCC color can be buffed out. Go to the paint store, 3M makes a number of high quality compounds, you can also get various off brands that work well. What you want to do is wet sand it out to 1500 or 2000 then use a compound that you can work by hand. You can really get a great shine with just the buffing compound. You can then finish it with polishing compound and a buffer if you want as well.

I've get more details on the buffing products that I use soon...

Status: offline 		Hay Mike,
Well I took your advice an used a white primer by Lusterkote. I resanded the color an applyed two coats o0f white an wet sanded each along with 3 coats of Missle Red with wet sanding between coats an still came out Orange. I thought maybe the momokote Missle Red was shinner then the spray so I put on 2 coats of clear. I am given up. will send picks of final plane when done but here is the Cowl an belly pan. An the same problem with the canopy. I have learned the hard way that Monokote an lusterkote do'es not match.

Status: offline 		Wendell,

The only way that I've been able to make Lustercoat match is to use the lustercoat primer, and then paint the object with white lusterkote, and then spray the color. If I'm not mistaken it says on the can to base all colors with a white lusterkote base coat,

I'd be getting in touch with the manufacturer if I was you. I'm sure they can sort it out for you.

Cheers
Jason.
