Epoxy>bondo>featherfill schedule?
 

In the process of painting a friend's '89 E150, the prep took me a lot longer than I suspected and I'm looking to make time where I can. The Eastwood epoxy we're using as a first layer has a recoat time of 30-60 minutes and a cure time of 5 days. It's going to need a good bit of bondo work to fill out some customizations - if I'm as precise as possible with the bondo is there any reason I can't apply it and the first coat of featherfill during the epoxy's cure time, taking advantage of the wet-on-wet window and saving the time to scuff sand the epoxy before the FF goes down?

Did you say 1989 E150?

Ha, cool! This one's a short panel w/300-6 that he's going camper/overland rig with. My sister and BIL bought one from him a few months ago ('86 Starcraft low-top conversion, 302/AOD) that they just took on a 1,200 mile trip without any trouble. Averaged about 14 MPG though. :D

Wanted to follow along with this post.

I just finished painting my truck with Eastwood epoxy. It was difficult to sand the car because the epoxy would gum up my paper.

This weekend I started spraying paint for my second project and was thinking of going from epoxy to high-build primer in one shot to ease the sanding process.

Most epoxies have a no-sand recoat window of 2/3 days, some up to 7 days. You can apply filler or primer over it without sanding within that window. After that they usually want you to sand and shoot another coat of epoxy before spraying other products.


SPI has a great paint step guide on their website.

This is generally an acceptable option. Please be sure to read the P Sheet or Technical Data Sheet of the products you intend to use to be sure it's ok.
