I've read about people using epoxy primer first before using the G2, and I know people that use G2 with out anything else first. Can anyone enlighten me on which way is best and why?

TIA

You can do the Featherfill without epoxy first for sure. It goes on thick enough to seal any loose strands of fiberglass. A lot of Vettes were done this way before epoxy primer was around.

IMO, epoxy first will give you a moisture barrier. For fiberglass, I would say that is the number one advantage.
On steel, I would say the number one advantage is the superior adhesion qualities.

IMHO Evercoat makes another product called Slicksand, that IMO works a lot better and sands much easier,may even be cheaper

 

Can this be done in one session, or does the epoxy primer need a day or more to cure?

I was just reading about the slick sand, whats the difference? Just higher build? Easier to sand?

 

I have used the original Featherfill but not the Featherfill G2 and I have used Slick Sand.

I liked the Slick Sand a lot better than the Featherfill. There was nothing I didn't like about Slick Sand and would use it again.

However, I have heard that the Featherfill G2 is good as well.

It depends upon the brand of epoxy primer. Alway use info from their particular product information sheet.

In the case of SPI epoxy primer which is an excellent epoxy and I highly recommend, take a look at this link:

It says to let it cure overnight in their "Perfect Paint Job" write-up. However, their P sheet gives you a window of 60 minutes to 7 days.

What is everyone using to seal the G2 or slicksand before color coat ?
Do you use urethane primer or another coat of epoxy as a sealer

 

I have had good luck with PPG dp epoxy thinned as per instructions as a sealer and it works out cheaper than what I was using, and it can be mixed to give you the proper shade needed for good coverage and color match

 

do yourself a favor and dont use featherfill, fi your car ever has to be re-done at one time when you have it, it'll save your bodyman alot fo work. (or yourself) featherfill is very hard to strip, it bonds well, but sucks in other aspects of getting it off. polyester the car and block it down with 180 ( almost to the point that it breask through) then prime it. it'll be easier to block aswell.

 

Featherfill G2 IS polyester.

It is a also a fine polyester to use. Sorry to blatantly contradict you on this, but you are not correct.

 

had no idea it was a poly. but featherfill isstill a b*tch to strip. i dont remember off hand what brand we use, but it blocks very nicely.

 

Featherfill G2 is easy to work with, in less than 48 hours. After that, say about 5 days, bullets bounce off of it.

 

Slicksand sprays out with a textured surface. Must be thinned down 10% with acetone and use a gun with at least a 2.5 tip.. If you don't thin it down, you will waste a lot time and energy and primer, sanding just to get through the texture. I learned this the hard way. On my latest car I did not use Slicksand but ended up spraying more Featherfill. Featherfil or the G2 are great. I've shot both. These are polyester primers similar to polyester which is used in Fiberglass bodied cars using the same exact hardener. Very similar to gelcoat but sand way more easier.
Now when it comes to stripping a corvette, Do Not strip primer. Primer on a corvette should be wetsanded off with a little soap in the bucket 2-4 drops of soap/gallon. lube and oil cleaning. Time consuming but better than subjecting your glass to stripper. If you have a stripper that is removing the primer, That is most likely tooooo strong of a stripper. Remember this is a fiberglass car.
I will never have another fiberglass part soda blasted again. Stripping is something a non-bodyman can do. Wetsanding again is the answer, it also assures you that all the stripper will be cleansed from the body.

Sealer: some people seal others do not. Another wasted step? If your poly primer is continuous throughout the surface of the body with no breakthoughs of the primer to body below then what are you sealing. Evercoat clearly states no sealer is needed when using Featherfill.
Read the label please and get the p sheets.
