Base coat over SPI
 
A guy told me he his buddy was thinking of sanding his car down and using some rage for the dings and such, maybe down to bare metal with 180 grit, then spraying spi epoxy over that then going to a base coat clear coat, whats his chances of pulling this off, and having it look decent, moneys an issue, he's just wants it to look have way decent.

Thanks guys.

Depending on the condition of the existing paint he may not need to go down to bare metal. The SPI epoxy is a great idea. He can apply the Rage right on top of the epoxy, no need to go to bare metal to fill those dings.

Thanks Vince :thumbup: then the other question, if he just sprays the epoxy on, and doesn't use a 2k over that just sprays his base/clear right over the epoxy will his paint job come out looking okay, or is he set up to fail.

I am pretty new to this, only doing it for about a year on parts.
I go directly to base over the SPI epoxy primer, either sand it down to 4 or 600
or try to lay a slick reduced by 20% epoxy primer to act as sealer and base on that. it is probably the best way to go.. let the epoxy cure for a least a couple of hours, or best, overnight. then just tack and go. the primer comes in 3 colors, so choose your weapon..

Worked for me!!!

The only thing that he should do is respray some more epoxy over any filler for proper protection. You will go to either the original paint or bare metal when the filler is sanded and feathered in. SPI recommends overnight cure - and from my experience, it is necessary as it will stay thumb nail soft for 4-8 hours or more.

I used SPI epoxy, then in some areas some spray polyester or 2K if I needed some minor fill then finished with DuPont Chromabase BC then SPI Universal CC. For the most part, the topcoats were over the epoxy
