sidecover paint on a 750 F
« on: November 07, 2010, 07:58:30 pm »
I got my new sidecovers for my 76 750F and am ready to paint. Has anyone used primer for plastic parts,  neccessary? What is a good grey color for them? The only thing I could find in search was Eastwood's pontiac rally wheel paint.
 They are Frankenbike's new ones and are really nice! Better get em while they're hot!

Most paint makers would recommend a primer.  I just painted mine (I have the same bike).  Used Duplicolor self-etching primer first, then Duplicolor filler primer (comes in 3 or 4 colors), then paint.  From everything I read, starting w/ the self etching primer really helps the paint stick to the plastic.  Good luck!

there are also primers out there specifically designed to adhere to plastic.  you should check you local autoparts store.  i think krylon makes one that goes on clear.  i have used it and had great results.

I used their medium gray (I think they also have a rust, black, and ??).  It worked great.  That primer is buildable, so I applied 5ish coats, then sanded it down to get rid of the little imperfections in the plastic.  Looks awesome! 

Oh, and as most members would recommend, when you choose a paint make (Duplicolor, Krylon, etc.), stick w/ it.  Things just turn out better that way.

For plastics, I scuff the surface with 300-400 grit sandpaper. Then, I use Dupont adhesion promoter before paint, but there are others, like Bulldog, in a spray can. The sanding is actually the most important step. Be sure to remove all mold releasing agents (Hot soapy water usually does the trick) before sanding.

I had to repair a crack in mine.  Sanded the cover with 400 grit and primed with Duplicolor primer.  Sanded this with 600 grit and sprayed on Duplicolor T169 black metallic followed by a clear overcoat. No problems.  This color is a bit more black than the stock phantom black which to me is more grey.

Looks good Steve! That looks like my side covers with a gloss clear coat on them.

Thanks for the info! It's way better to learn from someone that has done it than by trial and error!

I used the clear Duplicolor adhesion promoter, black primer and BGM0522 Storm Grey Met. I didn't get a lot of gloss but I don't remember them being that shiney new. It is a little lighter (more silver) But is very close and I am going with it. There is a chrysler and a ford version that may be closer but it's hard to tell by the color of the cap on the can. I could have done a little more wet sanding and saved some primer but I really love the side covers, I've been riding without for a long time.

No real gloss on a new set. Pretty flat. I just happen to have a NOS set  ;D

My originals were somewhat glossy considering the age.  Definitely not flat.  From photos I have seen of other F bikes it seemed that many side covers seemed a bit more black than mine.  I would describe my original covers as a charcoal color.  I wonder if there was some variation over time?

I'll try not to forget to get a picture of my NOS set and my clear coated set. I think my originals took on a little gloss due to wax and being rubbed by my jeans. Charcoal gray seems about right.

I rode it today and the Storm Grey Met. is a little too light, in the sun it looks silver not charcoal. I may re-paint with the T169 black met.

You could also just add some straight black to your "silver" colored paint to get the color closer. {unless it is in cans}
