Remove undercoat...or not?
 

Got the 1978 SC almost ready to get media blasted. I am just in doubt if I should take the effort removing the rubber undercoat. It is still in relative good shape and I will never be able to reproduce a good protective layer as the original undercoat.

However, I like the idea of starting with a clean tub.

At the end it will be a street and occasional DE/Track car. Maybe more tracing in the far future.

What was your guys motivation of removing the undercoating?

I would not remove the undercoat on this car it look to good .I do remove Undercoat 65-77 because most time i find rust and have to do welding .

If the chip/stone gaurd is still good leave it alone. On the other hand, are you paying by the sqft?:eek: Maybe just do what needs to be removed if any.. have them feather the edges and reaply new chip/stone guard. Check out past threads there is much info.;)

i did a full media blast on my '75, when it came to the undercoat section, I asked the plastic blaster to just do a once over lightly on it unless it came off easily or if there appeared to be a problem.

They complied, there were one or two spots they blasted off, but for the most part it left a very nice, somewhat fuzzy surface that I put the Sikkens OTO chipguard on top of.

That was close to 20 years ago....and it is still fine, no issues anywhere....
