Yamaha Paint Project

[Ludicrous]

Here's an old DIY project I did about two years ago. Feel free to ask questions about it. (got a new project everyone will love, in the works)

I did the same exact thing with my Yamaha about 4-5 years ago. I went to the auto paint jobber and got some PPG DBC. It has held up great. I even painted mine outside.

Sweet! Looks brand new! How long did it take to prep?

I think I would have used Epoxy primer instead of etch primer,,,,but both will work.

Did you use any sealer under the base coat? How about any hardner in the base coat?

Welding about 20 minutes, drop the lower unit and sand it about 30 minutes.

Yup both primers would work. The guy I used to work for was a pilot and also painted allot of airplane parts...he swore by the 1791 for aluminum. No sealer and no hardener in the base. Base color coat then a few coats of clear. Done.

Yeah,,,that is some good stuff. I used a lot of DuPont VariPrime,,Its about the same thing.

I repair a lot of engine cowlings for a couple of local marinas.

The SMC that they are made of is easy to work with as long as you use the right materials. Polyester products will not adhere to it at all!............

Ludicrous--I remember this thread and actualy wrote your color combo down in case I ever needed it. I don;t have a yamaha presently (but might again in the near future )and I remember afterwards you saying you would change the color some? Do you have that new mixture?

No formula, just a bit more 1687 toner to lighten it a shade or two.

I have a Yamaha cowling with a hole in it, about 1/2 or so diameter of damage. I hit something left in a rod holder as I tilted the engine up. Can you recommend a material to patch the cowling? Does this require fiberglass or can I use some kind of Marine Tex? Thanks for any information.

DO NOT use products made for "Fiberglass" repair. Polyester products like fiberglass resin WILL NOT! adhere to SMC (Sheet Molded Compound). That's what your cover is made of.

This is what you need for small repairs. Grind the inside and the outside of the cowling then apply. You mix it up and spread it just like working with Bondo.

Here is the link to it.

You will also need this before you apply your filler primer.

Epoxy and matting was used on the inside of this repair.
