Very true Shine, or should I call you "Porch Dog".....
but as you say, it once was acceptable to gelcoat FG/SMC that was
badly damaged. Not trying to be a smartypants in bringing up one
of your posts from the past, just thought your technique would be
informative in this one.

like john i have gelcoated older vettes with a lot of damage . in the late 60's it was your only choice other than featherfill . it is truly a pia to do. very time consuming. on the latest one i chose to do it a little different. after all the repairs i used only spi epoxy to resurface with. the results were a job that had 0 shrinkage or die back . i stopped using urethane primers years ago . by changing my system i now only use 3 products on a car. spi epoxy, ppg ss color, spi universal clear. it has worked very well and will be my system of choice from now on. hope this helps .

But since epoxy primer is difficult to block out, I'd assume a (medium-build)
polyester primer would be acceptable to spray over the epoxy, to reduce the waves inherent in SMC fiberglass...?

in the days of lacquer it was all but impossible to hide bodywork on corvettes. yes , we would gel coat badly damaged cars. one thing we learned is gel coat is the weak link and creates more problems than it solves. with out the mat it is very weak and prone to crack . then evercoat featherfil came out . worked much better than lacquer primer . today there is no reason to use gel coat . epoxy takes care of all the problems of the past. spi sands easier than many of the polyester primers on the market. there is no comparison between corvettes and metal cars. i have seen my share of destroyed corvettes pulled from body shops .

the hell are you guys spraying epoxy on fiberglass for!?!?!?!? LOL

anyway...cant go wrong with polyester primer or epoxy imo. i dont find the sikkens poly primer hard at all to sand...i just sanded some year old stuff yesterday with 180 and did just fine........but the spi epoxy is awesome also....using it on the 67 vette now. nothing better to put on a raw fiberglass vette body than epoxy....NOTHING.

Why can't I rattle-can it silver? I'm not looking for show quality, just cover up the yellow spots.
Its your car, you can rattle can it if you wish, or paint it with a brush, or burn it to the ground

Is this just a Corvette issue because of the SMC or is this applicable to other composite-panel cars? I'm thinking of late model F-bodies or newer trucks with the "stepside" beds. Do they have these issues too?

X2, you have it worse because full blown SMC.

Soak twice as much and expand and shrink twice as much.

Bondoking fixed his wifes truck box a year ago, he may have some choice words to pass along.

resin never sleeps . it cures . i have seen early vettes that crumbled. raw fibers hanging out. fire ants seem to like resin and will chew one up. 57 cameo bed had a huge fire ant mount surrounding it. had to be gel coated .
so when dealing with a 30+ year old piece of dry porous fiberglass it is important to remember it will suck up what you apply first. i would rather that be water. it will come out. residue from solvents or chemstrip will not.
