will there ever be a hi-build primer that can be applied over (and adhere to) aged and scuff-sanded factory paint instead of having to sand the original paint down to the bare metal? it would be worth $100.00 per gallon to save all the extra work! :rolleyes:

many primers fit this description, in fact almost all primers. And many primers are well over $100 per gallon, I tried one awhile back that was $65 per quart at bodyshop discount price, ($260 per gallon). You should never primer over a finish that is deteriorated, aged to the point it is cracked or delaminating.

High filling? Less than $100? Polyester, that's what. NOTHING fills like polyester primer, you could tape a quarter on the fender and bury it!
It costs about $60.00 a gallon with hardener!

Hey Brian,
Can Polyester primer be Wet sanded?
I remember in the old days, products like "Feather Fill" were not suposed to be sanded wet.

keep talking! this is very interesting! my '73 chevelle has the original black paint that isn't peeling or cracked, its just not up to snuff like a new finish.i had to do a little body work here and there with fiberglass filler but overall its not bad.i want a satin finish(almost semi-gloss.)can you guys advise me on a hi-build primer over the original finish for a basecoat/clearcoat job?i don't have much time before cool weather sets in.thanks!

Remember guys, this stuff is VERY high filling. It is a specialty primer that should only be used if you really need this high filling. Urethane primer is SO much easier to work with.


If I were doing a "suede" finish, I would want a nice urethane primer that was sanded as a base for the suede color. That way, I would know that there are not going to be any surprises.

Brian,
Thanks for the reply.
I was just curious. I worked for a couple different Jobbers from 1977 up to around 1986, then I was a painter until 99 or so..
When I worked for a jobber here in SLC, we sold TONs of feather fill back in the day, and if I remember correctly, wet sanding was NOT recomended.

thanks MARTINSR! graemlins/thumbsup.gif
