This is my first use of SPI products. I DA'd the car with 180, blocked with 180. Washed her with Dawn and distilled water. I will mask her today and get her up on stands. I will final clean with 710 then 700.

This afternoon I will shoot 6610 Epoxy. I was thinking one reduced coat since there are just a few break throughs and I need to seal the original paint. Or should I give it two full coats..? It is humid today with a large chance of rain...

I will be following tomorrow with High Build primer for blocking with 400/600. Or... should I apply to full coats of epoxy and block that (see above)? Then PPG DBC (3coats or 4 for coverage) and Universal clear (3 coats)

All comments are welcomed.

Always interesting to see how new products react to your spray room conditions...

My favorite engine, when wife and I started dating I bought her a 64 but it only had a 383 in it, paid 175 for the one owner car and it was a fine car, if it had been a wedge or Hemi, I would still have it, I'm sure.

Do not reduce the epoxy, spray two full coats before primer.
 
Thanks Barry. It is an old school neck snapper to be sure...!

2 full wet coats and the high build?

I did not get to spray today. Left the booth doors open for a couple hours in gnat season... Had to pull the car out, bug bomb, yadda yadda yadda...

I hate bugs In my spray area worse than dirt!

GS
 
Bugs?? Worse is pollen, I'm redoing 50-6"x12" test panels because pollen landed in the epoxy, what a screwed up mess!
 
Barry,

Get some honey bees they will take care of the pollen problem.
 
Barry... your recommendation is 2 coats of epoxy. Should I block that or continue on tomorrow with high build for blocking? I do not know the sanding characteristics of either product.

Two coats of epoxy is going to be your best bet to seal out that 49! year old paint, strive to keep at least that much epoxy on the car throughout the process. But no doubt at some point down the road there will be failures related to that 49 year old paint-how long it will last is only a guess. At a minimum I'd strip the exterior and just freshen up the jambs-a few weekends worth of work might add 20+ years of life to your work.

My thoughts as well. If it were mine I'd strip it and and shoot two coats of unreduced epoxy for a foundation that will last longer than me.
 
I have been spraying epoxies since my structural steel days in the 70s. I typically use PPG DP90 and have been quite pleased with the results since the mid 90s. The SPI epoxy may very well be the best I have ever sprayed. Nice stuff.

Then sprayed 2 coats of high build primer. Also nice stuff...

I will block it again Monday or Tuesday. 600/800?

i used dp for ever. when the dplf came out i was done . had i not ran across the spi i would have retired years ago . i use the epoxy as my build primer.
 
Let her sit all week end. Dry blocked with 220 grit this morning. Washed her down and wet blocked with 400 then again with 800. Seems to work much like
K 36. Not quite as much sheen but, still very nice. Broke through to the epoxy on many edges, some in the field. Most of the remaining primer is quite thin. Washed her down again and blew dry. Left fans on and will shoot a reduced coat of high build in the morning. Then a final soft block with 800 in preparation of finish coats on Wednesday. I like the products very much. Can't wait to try the clear...

I'd roll it out in the sun for awhile considering the old paint underneath-if it soaked up solvent it'll eventually purge out and sooner is better than later.
 
Bob

It sat in the sun all week end. If you think being out longer will help, I am not in that big of a hurry. I can certainly wait until next week, or later, if needed.

Might go ahead and try the clear on this in the interim

The sealer adds a lot of durability, adhesion, chip resistance.
