Painting

I am nearly finished with the initial sanding of my car and getting ready to put it in primer. I have heard about a roll on sandable primer sealer. Anybody have any info on this product and the application. It seems to me that it would make a mess of the sanding I have already done. It would save me the trouble of taking the car to the paint booth to prime then bringing it back home for final sanding.

I'm just a little ways behind you Randy. Just took posession of my ERA 647 and I've taken the edge off the mold seams. Needs a bunch more sanding and some epoxy filler before I even consider the primer. But I'm reading up. And I know I should put an epoxy primer on after I get it all sanded. Just not sure what type and where to find an epoxy primer.
There seem to be a multitude of "spiders" or "stars" in the gel coat. I don't think the mold was either cleaned and prepped properly or the application of the gel coat was pretty hastily done.
I thought sand blasting them to get the crud out and a good surface for bonding would be smart.

Any thoughts guys?

One other thing. What do you think about the rubberized undercoat for the wheel wells? I was thinking of keeping the bottom "clean" but coating with the clear 3M for rocker panels.
I'd like to protect the fenders though, from rocks and gravel.

any help appreciated.

Rowboy,

Those "stars" are (un)fortunately in our mold, not in your gel coat. You can treat those areas just as you would any other section of the body.

Don't sandblast you could distort the body and cause you more problems. Bead blast if you must.

Epoxy primers are everywhere automotive paint is sold about $70 gal plus about $30 for the catalyst and I like to use a yellow color so when I do put the primer on I am and blocking it out again I know how deep I am going. I love that hand sanding!
Be sure and clean you paint gun and equipment with lacquer thinner as soon as you finish with your painting otherwise after a couple hours your paint gun will be junk. At $200-to over $1000 for a paint gun it would make that primer coat very expensive.

I like DP 90 epoxy primer, I've seen people use a couple of coats on their frame and nothing else, looks like powder coating and very tough. Keep in mind it's
also hard to sand.
