Being out here in sun country cars are generally rust free, but the sun damage can be horrendous. This is a summary of how I repaired my dash.

First the condition when I started:
http://i1180.photobucket.com/albums/x413/MikeJinCO/Dash%20and%20Interior%20restoration%20Porsche%20924/CopyofDSC00803.jpg


After some research I decided to use some easily sandable plastic bumber epoxy repair filler. I got mine, Maxim by Evercoat from Eastwood, 3M has a similar product. It is a two part epoxy in a caulking gun and takes a high pressure gun to get it thru the mixing tube. For my purposes it worked better to just use a regular caulk gun and mix and apply it with a tongue depressor. I first cut the gaps wider to give the epoxy more area to get a good bite per the directions.



When applied and sanded it came out like this, 80 and 100 grit sandpaper was all I used.







I then decided since the top vinyl was extremely brittle I should give it a new surface so I took some of my epoxy and 2oz fiberglass and applied it. I've worked with this for 30 years on curved surfaces and it would be very difficult to do a very good job on the more curved front surface.



Then since the surface had lost most of its texture I went to the truck bedliner spray and gave it a good shot which works well, but appears somewhat damageable.

I then painted the finished surface with SEM Graphite interior plastic paint as with my recovered seats the graphite works better than black.





So it is definitely not perfect, I didn't try to fill the warping up near the defrost vents, but it does look pretty good, probably a 6 or 7 out of 10. Will it hold up? Who knows? A good vinyl or leather recovering would be much better, but I'd rather spend that money on some HC pistons.

Thanks, but it actually looks better in pictures than up close.

Still looks as good, if not better, as the pic of my $400 so called professional job, that was in better starting condition.

Great job modest Mike.

A very effective and inexpenisve repair job.

The other option is to send your dash to www.justdashes.comand get them to do it....but I think that costs about $1000 to restoore a dash.

Well, x years later some of the cracks have opened up again. The places I put the fibeerglass on are fine, but 2 or the front ones have opened up again.

Sorry to hear that. The same has happened to the two dashes that I fiberglassed as well. I've been thinking about making a kick-starter to fund making us some solid fiberglass dashes that will never crack.

Where I fiberglassed it is fine, I used some 2oz fiberglass and WEST epoxy. Heavier glass wouldn't drape over the curves as well as it is less flexible. With as many curves and corners the dash has it would have to be set up for either vacuum bagging if using cloth or probably a chopper gun for fiberglass. I don't know if I could get any matte to conform to the shape as I really haven't used it that much . We are taking off for the winter to South America in November but would like to work on it in the spring.

Here's mine
I filled in the cracks with structural adhesive )3m Automix 08115) then used a dash cap and bonded that on with the same structural adhesive.

had you thought of a loose weave like woven rovings? something that will bunch up where you need it to and expand in other areas... then apply a body filler over the top.

I normally get into my curves by tearing light mat and blending the edges, just have to make sure the mat has plenty of resin to wet out properly.
