Firewall Restoration

[upscope757]

All,

Recently had my body blasted then laid a coat of the epoxy primer over it. I am ready to shoot the firewall and was wondering if there is any straight forward way of sanding it to receive the paint. Any kind of orbital or vibration sander appears impossible to use. Sanding by hand seems to run the risk of creating an uneven surface prior to paint.

Might be over thinking this. Is hand sanding sufficient? There is some peel with this primer and the primer is not forgiving. It is going to take some work.

Thanks,
Matt

 I shot epoxy primer (DPLF) and then some primer surfacer (DPS) and sanded with 320 grit by hand with a soft block.
The surfacer should help smooth the peel.

Thanks Mike.

I don't think your supposed to sand epoxy primer and there is a time limit when topcoat needs to be applied for the chemical bond to take place. If you are past that time it might need a light scuffing. Just what I have been told and practiced
