I use the mask w/ the DA. but most is done with blocks and no mask. Lots of black booggers.

 

that means im gonna end up with yellow boggers im gonna be using the buff colored primer i find its easier to find my low spots when blocking with the buff.

 

I chose black epoxy for a reason kind of like that. I can drive around w/ a black semi gloss car and people with think I did on purpose. Then when I paint it I will use gray 2K. It will show the high spots as black. Then silver on top of grey is easy.

 

yeah damon i never thought of that,i like the black primer too but thought this time i would give buff a try,i havent used black primer in years,but thats whats under my factory paint,its weird they used black primer on the orange.

 

My blue Z has buff on it. It is freaking on there too. i was sanding it with 80g and wasn't getting very far.

 

I'm 99% done sanding black off. I'll be ready to prime and block. This means I have to get off the pot and decide what the back spoiler will be. I spent some time shimming and playing with the holes to get it as best as I could. I can probably live with the fit to the corners, as you can't notice unless you lay your head on the quarter. The height difference from the corners to the middle won't work though! It is slightly off along the back also.

 

I started sanding to see if I can make it fit.I'll have to address the thickness change when it's off.

 

looking better its getting closer i think u should be able to get it close enogh by sandying,nice progress its really goona be sharp when ur done,cant wait to see it painted.i been thinking about the one pice spoiler for mine if i can find one in good shape,like the 70 camaro had,i want the tall one.all ur hard is payiong off,its gonna be real nice when ur done.

 

Thanks BAD. I'm plugging away. Another month and I should be painting. I still havn't decided who will be painting. I may spray the red base and just send out for clear. the base I can sand any thing out or even respray as necessary.

 

I'd be sure to get some fibberglass resin and recoat the open sanded areas once you're done, if you break through the gel coat. Otheriwse the open pores will create issues with whatever goes over it, and might draw moisture if it's not sealed with fiberglass resin.
You might also want to build up the back side of the spoiler underneath to help make the gap less obvious. I'd lay some vinyl shelf paper on the quarters and then apply Duraglass to the back side of the spoiler corners. Bolt the corners down and let the excess ooze out, then wipe it off pressing it slightly back under. Once it dries you can pull it off and remove the shelf paper, then sand and prep it. That should remove the void, and keep water and dirt from running out every time it gets wet, or washed. Plus it will make the void disappear pretty much.
