A friend has a Whitewater machine which has the infamous problem with the ball coming out of Lost Mine causing major wear on the playfield near that outhole.

I need to touch it up but may also need to put in some putty (plastic wood?) as it has caused the wood to go down say 1/2 millimeter there.

What do I use (Plastic Wood)?
Do I use acrylics or oil based touch up paint?
Then I could apply a small circle of mylar there to project the final finish.

I got these small circular pre-printed mylar discs from EBAY to use as a finish but I don't like the quality of the paint color (it shows dithering in the image also - especially purple).  If you are a user, you can view the Complete Item: 6224697163     to see what I mean.

Thanks in advance for any opinions on this.
Merci Bien.

I've actually did that exact same touch up on a whitewater.

Don't fill it up. The paint will be enough. Put enough coats.
use acrylics paint only!

Mylar: Omer Deserres sells transparent vinyl by the foot that is perfect for that. I can send you a piece if you want ?  (pm me your address)

Hi there,

I did some gouge touch-ups on the HH I recently restored and I used a structural epoxy for the deap ones, I used a bit of plastic wood for the shallow ones, but I don't think it's strong enough for spots where where the ball actually drops from a bit of a height.  If I do another one, I'll use a forstner drill bit and sink it 3/16" or 1/4" into the damaged area and then fill the hole with a matching disk of good hobby plywood.

As for touch ups, I airbrushed acrylic, and it works well because if you don't like it, you can wipe it off with alcohol and try again.  It must be cleared, or mylared over though.

Mylar disks will effect the ball path a bit though, you'll only notice it when the ball is moving really slow, but it's there, and I used a really thin mylar I bought locally from a label making buisness.
