Krylon Confusion

Hey Guys,

I'm in the middle of a painting project on a Dune Racer and would love some advice. I see a lot of useful part from the past but people's methods vary along with my mistakes already made have me unsure what to do next.

I sanded everything down with 400 grout for paint prep. Which want to bad except for the rims, man what a nightmare trying to get all those sanded down, that too 90% of my time, I would have left them the fake chrome if it wasn't already half flaked off. Hopefully they turn out ok when it's done.

So a lot of time had passed between when I looked for advice on this board and started sanding and when I finally finished sanding the evil rooms and them remembered I needed paint when I was in Lowe's. I purchased Krylon Fusion paint but also the Krylon bonding primer that states hard to bong plastics as one of its uses.

I dusted all the parts with bonding primer, two coats but the original color was still very much showing through. The did base coat, dusting for two coats and then probably 4 more coats. Then moved on to clear same procedure. All coats were about 15-20 minutes apart.

So during the process I realized the color I picked on a whim in the Lowe's ailse looked terrible, to me at least. After a couple hours I decided I for sure was not going to leave it and started sanding. It is all stuffed up to a dull finish with 400 grit waiting for a second color choice.

So my questions...
I am supposed to wait a week, preferable to before recitation. Does that apply to the next session also or just after the first session the was bonding to the plastic?

Did using the Krylon bonding primer, as I now know if not advisable affect wait time as it is what is primarily bonding to the plastic?

Is there any reason to continue to use Fusion since the plastic is already covered completely? Then could I use say Rust-Oleum and have less wait time? I am thinking about making of and two toning the flared up parts on the fenders.

I did some pieces in matte black including the hood which looks decent but splotchy in some light, is there anything I can do to get rid of it? I tried sanding it down lightly after 20 minutes, cleaned and recoated but it didn't seem to help much. It also seems to have quite a bit of shine, would I have better luck with a different brand of rattle can?

Any suggestions for paint scheme?
I am thinking now about doing gloss white and clear coat for fenders, rims and steering column, leaving flat black for hood and side tubes and leaving gloss black for steering wheel, no idea what to do with seat.
Also thinking about doing just a total blackout and make everything flat black except steering wheel and rims in gloss black and call it the batt-mobile.

Any help/ input is appreciated.

Thanks

I went ahead and continued painting on the Dune Racer and it is shaping up a lot better than the first attempt. I went with Rust-Oleum 2x this time after reading several good things about it here and the much less wait time to recoat. I still have to put more clear down on the white, store only had 1 can and I didn't go very far. I also need to paint the seat still but I can't decide what color it should be. Any suggestions?

I'm also more concerned here about adhesion because of the textured and high wear surface. I had a lot better results with Rust-Oleum than Krylon finishing nice especially with flat colors, which is what I am leaning towards. The Rust-Oleum 2x states also bonds to plastic on the can. Can anyone with experience chime in and say how this paint has held up on a high traffic textured area?

This is just laying some peices in place to try and visualize what color to pick for seat.

Hi, looks good. I have always used duplicolor paint and I spray on their adhesion promoter befor it make it adhere better. I personally would do black or a tan for seat it will stand out nice but that’s my 2 cents.

Thanks, too late on the paint suggestion though, painted that last night. I was thinking black but the wife thought grey or white, so grey it was. I hadn't thought of the tan, that probably would have looked pretty good. It's possible it will be changed if I don't like how it turns out.

I'm iffy about changing the bumper again. It was good black to start with, I thought it might look cool contrasting the flat black hood but I didn't like it once it was done, that was also before I changed the body color from Orange to white. I went the opposite and made it white because I thought the fenders turned out great but I'm not sold on it either. I'll see shortly once it is all put together.

On the other hand it is going to look a 1000 times better than I found it and my boys are starting to get very anxious to take it out now they see it coming together.

My last painting session should be tonight if all goes well and I don't change my mind any more. I am planning on painting the 3 raised doo-daws on each front fender. Have them make of and ready but am a little unsure of the procedure and found conflicting information about when to pull the tape.

I have read to wait a few hours so everything is set but have also read to pull it as soon as you are done spraying. Right now my plan is to go light on the paint see if only two coats is enough and pull it after about 10 minutes or when it looks like it's starting to flash.

I’ve painted most of my stuff with krylon fusion and have good results. Now i haven’t gone all out and painted a full body. Mostly i paint all the plastic accessories (seats, bumpers, roll bars). Most places don’t carry it anymore so I have to stop at my local Sherwin Williams store and sometimes they have to order it depending on the color I want.
Yours looks good though, I like the color scheme. I would second not using black on the seat. I have a mustang that I painted the seat black and I always have to remind the kids not to park it in the sun on on bright sunny days or the seat gets pretty hot. I don’t think it gets hot enough to burn them but it’s enough where they complain and I have to drag it into the shade for 5-10 min to let it cool off.

I'm sure my issues with the Fusion were self inflicted. After my first attempt not looking at all how I hoped the color looked though I didn't want to deal with the minimum 1 week between coats if I couldn't do them consecutively. I am still curious if that only applies to the first session that goes directly to the plastic or if it is also following that. The fusion definitely seems to bond well. When I was sanding it after it seemed like it was the actual plastic not a paint coat. But after using the Rustoleum 2X it seemed to go on a lot smoother/easier and it only recommends 48 hours wait before coating again. It is all looking good enough for my first time, I am just really hoping it will hold up to the abuse of my two boys and the rest of the neighborhood kids for a little while at least.

I mispoke when I said I was painting the body, I am leaving all the old black body pieces and am going to just sand out the chalky parts, probably tonight. I have done that on a few rough looking ones before and it has turned out well if I just go rough enough to where the white stuff disappears and then work my way back up to compound. It is also a lot of work but I am now convinced it is less than a paint job. I will probably put the Dune Racer into operation before I finish that, that back is sun faded pretty decent on the top.

As far the black in the sun I think it should be ok. The Boys are pretty good about taking their rides back to the garage and plugging them in. They feel like they have an important job to do I guess. The flat black is more likely to start looking rough from abuse I am afraid.

I got the accent flare things painted on the fenders last night, as well as the fake front springs and the new shifter I got in the mail yesterday (the old one had the handle missing when I got it). Tonight I plan to finish wiring in the back once my 18v charger port shows up and I get that soldered up and re-assemble.

I am mostly happy with how it is turning out, I thing I want to do something different with the Power Wheels badge on the front but I am not sure yet, maybe brush paint the raised outline and lettering?

Let me know what you think.
