Bondo/Glaze Putty/Primer

[Shelbyco427]

Could use some constructive weigh in please. I received my Roadster kit the middle of May and decided to prep the body, the best that I could, before I took it off and set aside for the build. I ground down the seams to where I could apply my initial coat of bondo to fill in the low spots. Some of them seemed totally set after the 1st coat but I couldn't really see it that well. Here is where I hope I didn't screw up. I sanded the areas thoroughly with 320 grit after initially hitting the area with Prep All. I wiped it down real good with isopropyl alcohol and then hit it with a black sandable primer so it would show be any low spots. I hit those with glaze putty and then sanded them down to a feather. I'm wondering if that primer is going to be an issue once I send it off to a body shop to do the final sand and then primer paint?

I've got two pictures. 1st is the panel that has that primer still on it, and the other is the top right seam that I was thinking of hitting with primer to see if there is anything further that I need to fill/sand.

Any thoughts on whether good/bad or whether it will/will not affect the paint shop when they receive it?200270200271

The best thing for you to do is stop now and do nothing more.

Like Jeff said I would stop where you are at and get to work on the chassis.

Most body shops do not like finishing other peoples body work. There is also concerns on the type of bondo you used to fill in as some do not flex well with fiberglass as they are designed to be used with steel panels. This is just going to lead to cracking and frustration of your newly painted car down the road.

If you do have a body shop lined up I would really recommend having this conversation with them. As like I said you run the risk of two ways this goes. First body shop refuses to do the work or second they charge you an arm, a leg and your first born child to correct it. If they are good bodyshop they will go over with you exactly how they want this to be when they receive it. Also take this time to shop them as not many are familar with these cars and you are going to see some sticker shock as well (I had one shop quote me $30k for paint and body work).

When you do find your body shop make sure you tell them exactly what fillers and primers you used already as there is a good chance they are going to grind it off. Also ask them what they plan on using. Jeff has a great thread on the body work you can use for reference when asking questions of the shop. It was worth its weight in gold to me when I was lining up a shop. Below is the link (Sorry on that "other" forum):

Elsewise don't be afraid to ask before cutting and grinding. Great group of folks on here to help you in that direction.

Good luck and happy Building

Just for clarification, that thread is REALLY old and some of what I said &/or did back then is outdated and not like how I do them now...one of those constantly evolving things ;) It does illustrate the scope of work though.
