Rustoleum substrates

Hey guys, I have been using Rustoleum on my last couple of planes and I used Aero Gloss sanding sealer sanding between coats (3 or so) and it works good but I am looking for a cheaper and equally light substrate. I did try Rustoleum primer and sanded it down between coats (1 light then 1 heavy) but it seemed to add undesirable weight.

What are you guys using Rustoleum using as a base?

I have been using the Sandable primer from Rustoleum as well. You can use any sanding sealer though, giving it enough time to gas out. You could use one of the Water Based Polyurethane sanding sealers too.

By the way, you don't have a sister named Sadie do you? I think she asked me out one time.

Thanks William,

Did the sandable primer come out heavy? Would I find water based sanding sealer at the local hardware store?

I do have a sister, Juli, married now with two teenage daughters... All of them beautiful girls.

Cranemon, Phil may never have heard of Saddie Hawkins Day...sad. I think it came from the Lil' Abner comic strip. It was a (bad) joke, Phil, and you messed it up perfectly (good job!).

I would definitely try MinWax PolyCrylic (aka "PC" on SSWF) with some Corn Starch added. I've used the PC, and it is a "breath of fresh air" (another pun, beware!). Can't smell it at all, washes completely out of brushes with near zero effort. No complaints about sanding, dries overnight, goes a long way, thin with H2O! However, if Randy P. is to be trusted (he is), it's not too good over open bays without at least a couple of coats of shrinking dope under. One may wonder what would happen with Polyspan, which is a heat shrink. We need some testing and published results! Steve

Ok! I thought that name sounded familiar!

I just did a Google search on Sadie Hawkins and learned more than I ever expected!! I even now know when the first "Sadie Hawkins Day" occured... Kinda reminds me of that old song "If you wanta be married for the rest of your life better make and ugly woman your wife..."

Minwax PC... Got it,(PC that is...)

HEHE I wus bein so educated.

Figured you probably had heard that line constantly since childhood, oh well.

At least we have you on the right track for filler coat.

Steve,

Any insight into the adhesion of the PC/filler over epoxy/glass covered wood surfaces? How much filler is everyone using? Has anyone tried laying down carbon veil with PC? Half ounce glass with PC? I wouldn't mind getting rid of the epoxy completely. I'm looking for a better way to reinforce and finish a Profile Oriental fuselage.

I did not realize how wonderful this stuff was till I found a few cans on ebay. $127.50 for a 1957 can of green, ebay #3669782547. I thought emotion was bidding up the prices of some of the C*x engines. I wonder how many of those cans I have thrown away?

That is really dumb.
Chris...
