I successfully installed my Wizard Hardtop and have to say it looks and plays awesome. I've also read most all 32 pages of this thread and its interesting to read some of the results.
Couple of observations.....
Fist off, preparation is key. Dust or crap under your inserts are lack thereof. In my instance my inserts were not salvageable so they were removed and replaced with new. They are stunning and theres no gap, the hardtop is completely resting on top of them. If I could salvage the inserts, I would have sealed the insert from underneath so there is no air gap. You'd be surprised how much air is getting in-between that space where old glue is shrunk, gone, or the insert has shrink just a tad. I would recommend gluing the entire insert in place if they can't be removed/replaced or re-seated flush. This is also a place to trap heat. Not good for the insert or the hardtop.
If you didn't wait a few days after sanding, cleaning, gluing, wiping with Naptha, cleaning the area, clearing the inserts, etc. I am assuming this is where some ghosting could be coming from. Off-gassing is a b*tch.
I purchased a small trim router from HF(I think it was $28) and a trim bit($8) from Lowes. It was perfect in routing off any excess Hardtop. I used it in every light/mech/etc. hole and even on the outside edge of the PF. I had a small lip on one side and took that off too. Clean look, and everything was 'fitted' at that point.
I addressed the kickout hole at the top and the shooter lane by standard practice of repair. They were a little chewed up. I cleared those areas and painted them 'wood' color. I then cleared them again. Seeing old dirty wood under the Hardtop was not an option, the contrast between the bright brilliant colors and the old wood was just plain bad. It looked much better with 'faux' wood color than the beat up stuff. If the wood was in better condition I wouldn't have done this step.
I also painted black around every insert(for replacements only) as well as brown around any rollover lane or holes that accepted wire guides. These too were cleared after painted. This way the holes looked fairly uniform if the Hardtop was a little misaligned and the eye is not distracted by odd variants of colors.
I would also not recommend cranking down your screws and bolts. Snug is good. Remember some posts left negative indents on the PF so all your doing is compromising that slight gap. It would put stress on the Hardtop unnecessarily.
Added a pic just for yuks. Yes I know the top apron is bad but finding that color paint may be impossible as well as replacement bottom apron decals since Pinball Rescue no longer makes them
Next up is a coveted Evel Knievel and I hope this one comes out just as good! Thats for making these, what an amazing product! IMG_2998 (resized).jpgIMG_3001 (resized).jpg
