Any thoughts about the best methodology/products to paint a plastic fender?

Here's what I have come up with so far but have not tested it just yet...

1.) Wash fender thoroughly and degrease.
2.) Sand lightly all over with 600 grit paper
3.) Wash again
4.) Spray on Adhesion Promotor and let dry
5.) Spray on Krylon Fusion Plastic Paint and let dry
6.) Spray on Krylon Fusion Plastic Clear Coat and let dry

Krylon Fusion Paint --> Krylon: Products: Fusion for Plastic


Will this look good and be durable long term?

that will look good but chip and crack over time good luck

About the best you can do with no urethane paints. If you used automotive paints you could throw in a flex agent into a regular 2 step urethane, and throw on loads of clear.

Remember the year TLD ran strange orange colored bikes? All painted.

Won't last forever, but it can look good for a while.

I had flat black Fusion on a dr350 off road for over 2 years ( about 1 month after fusion came out) just sanded the sheen off and painted. no cracks yet. No adhesion promoter or primer. 5 minute job.

I tryed krylon fusion on the front number plate of a ttr 125. the only prep work i did was washing it. the first coats worked well but the it started lifting and cracking. So I sanded it and tryed again and it did the same. So instead I used Rustoleum Universal spray paint and it worked great.

if ur gunna do it DO NOT use 600 grid sand paper...u gutta use like 1500-2000 grid...****s like paper!..scuffs it up enough to give the paint somthing to stick to and u wont see a bunch of swirley marks on the final product!"as u would if u used 600 grid" good luck homie!

I just painted a new z50 fender black that was red!
1; washed fender
2; I used 220 very light!
3; washed fender down aagain after done with sand paper!
4; I used a rustoleum black high gloss! The bottle with the new trigger spray!
5; made sure it was good and dry and it turned out great! Wish I would have went with about 300-400 grit but looks good!

flex additives go away after the paint is cured. its only for putting flexiable bumper parts on for crash shops. but urethane paint is flexiable anyway, and if u can bend a fresh panel far enuff for the paint to crack, u have other problems....

1500-2000 is only for colorsanding and buffing. doesnt leave much too. while 600 is a little rough for plastic, it can be fine. 800-1000 would be the ticket. but i would never waste my time with a rattler can any way.

seems like you pretty much got but i would highly recommed spaying some primer after the Adhesion Promotor. them wet sand the primer with 800. youll get better results (i make my living at a body shop)

aj191

i say go for it!

u dont specifiy what primer? lacquer, epoxy, 2k uro, 2k dtm, etch, 2k sealer.

in all actuality it doesnt matter what they put on it, its all spray paint anyway, it will look like **** and wont act like auto paint anyway.


i make my living to with paint, but as a custom painter.

some good quality rattle can 1k surfacer. u can get it at your local automotive paint store, ive used SEM and spies hecker, work great, even if its spray paint it will stick better to primer and just spaying on the plastic,

1k is junk. dont care of the brand. but who cares anyway, its gunna rattle can anyway. 1k doesnt touch any of my paint. just causes problems later on.

Krylon Fusion or the Rustoleum version over plastic is pretty durable actually. I used it on a cross country enduro project which has now done about 3K miles off road, including a lot of sagebrush and the like and it seems to be doing fine.

I used a hammered silver on my fenders.



I did a very light sanding of the plastic with a 400 grit wet/dry sandpaper to rough up the glossy finish, but that was it.

The fender has been severely tweaked on a number of occasions and the paint does not crack or peel either.

YMMV

Slick light/turnsignal mount/bottle holders, and the hammered silver on the fenders looks cool. This is an interesting thread. I am a bottom-feeder scum job when it comes to paint; rattle cans meet my needs for dirt bikes, so this is inspiring.

Didn't you use fusion yellow on your boy's Z50, too?

irock

i might paint my bike now too

makotosun

I did use the fusion Yellow on the z50. He is now riding it, and it seems to be pretty durable. Goes on really nice too.

The light/turn signal deal was done for a specific purpose built bike. You can read more about it and the purpose at TAT Vintage Riders.

If you have more interest in the project, PM me and I can get you some additional links on our last year's ride.
