Dash Repair (Pics)
Well after much patience and searching I finally found an excellent example of a dash for my SC. The only issue is that the mounting bolt on the far right passenger side has some rust and is barely hanging on to the dash. Have not seen this type of fix in any of the threads and tempted to just epoxy it in as is to keep the bolt position lined up where it needs to go - any one have any experience with fixing something like this?
Thanks! Mike

i have not done such a fix. if it were mine, my thinking would be the same. i would probably buy as much JB Weld as I thought I needed (alot) and patiently layer and sculpt it into place...i would want to make sure the bolt/screw is at the correct position before it dries
 how does a dash get that rusted and yet look so nice on the top? strange

All I can figure is a lower windshield leak that worked its way in there over time. Since this dash looks great on the top probably make sense to go the path of least resistance and just bond it in place - never used JB weld before but I see alot of folks use it for pretty much anything so it must be a good product
Thanks!

I did a similar repair and used gorilla glue. Gorilla glue is a Polyurethane glue and it really stick well to the dash foam. When it starts to dry it foams up and fill cracks.
Good luck, John |

That center vent looks a little large for an SC...

Thanks for the responses - I'll let you know how it all turns out - thinking Gorilla Glue at the moment since it seems like it will fill in some of the rust cracks. Another couple pics of my baby-anticipation!!
Thanks!! Mike

Are you going to do anything to neutralize the rust first, so it doesn't continue to eat up the dash? As the old saying goes, "rust never sleeps..."

I do have some POR Metal Ready as well as POR itself - might be a good idea to put those on before I go the Gorilla Glue route??

I would use a marine epoxy such as west system, system 3 or something similar. I like the Gorilla glue idea but it will be difficult to control the expansion and it sets pretty quickly. You can thin the marine grade epoxy with acetone so it will seep into the pores of the foam on your dash and create a good foundation and temporarily secure the bolt so it wont move from it's location. Then you can use thickened epoxy to more securely attach the bolt. Each epoxy system has multiple thickening agents depending on the application and strength needed. Quite frankly for this application you could thicken with some fine saw dust if you have it to save a few dollars. Marine epoxies generally have an open time from a few minutes to hours depending on the application and the amount of time needed for a particular project. What I have described is used all the time in marine repair. the hull and or deck of a boat is made of a skin (generally fiberglass) and a core (generally foam or balsa wood) when a hole is drilled to attach a fitting (a bolt or screw) it will leak over time and deteriorate the core. This method is used to bond the damaged core and then bed a new fitting. Keep in mind the tension placed on a deck cleat or mast shroud far exceeds that of your dash screw so this repair will be more then adequate for your repair.

I would definitely use the metal ready, and then the POR.

OK - here's my thinking after digesting the responses: Ordered a small West Systems epoxy kit ($12), In the meantime I'm going to apply the POR Metal Ready thoroughly - let it dry completely then POR it all. Once that sets up for a while will apply the West kit epoxy and see if that does the trick. I decided against the Gorilla glue because it expands as it cures and I don't want any movement here.
Will keep you posted. Thanks a bunch! Mike
