if you are painting it w/ a modern eurethane paint, you dont need a flex agent. If you are going w/ some old school enamel or laquer then yes i guess you would need it.

^ this is true. I forgot to mention I did not use any flex agents while doing my paint job.

And to add to what I said about getting them if you can - I was told this by a painter I know, who is familiar with the system I used (Dupont ChromaPremier) and it's what the spec sheet says.

Too early to tell, but it's been 2 really cold months where I've driven at least 4 days a week, and the fiberglass parts have been OK without it.

If I could have gotten a sane amount, I still would have used it. It can't hurt.

Truthfully, the main purpose of flex agent is for re-installing flexible bumpers while they are still fresh. Flex agent actually leaves the paint over time along with solvents. After a few months "flexed" paint is no more flexible than "unflexed" paint. If you ever see a paint salesman demo flex agent with a painted soccer ball or plastic shower curtain, its a gimmick. They mix the f.a. at almost a 1:1 ratio with the clear, takes that crap days to dry fully.

burmashave, so basically the flex agent helps the paint bend along with the bumper piece during installation before the paint finally cures?

Yes...I learned this too. The flex agent makes the paint take longer to fully cure, thus staying flexible for assembly. Or something like that. Burma can give you the correct terminology.

This is an old thread...you didn't paint your car last year then?

V2Rocket

no. moneys have been nearly nonexistant for some time.

harrisonrick

ahhh school.

Burma Shave

Bingo! Even when you way over do it with the f.a., like the soccerball demo I mentioned earlier, after a few months it will crack when you bend it.

DarylJ

Ahhh...now that makes a lot of sense. Thanks the for explanation!

So much of the paint systems are geared towards getting it done fast in a high volume paint shop....which makes sense considering where 99.9% of it ends up.
