Frame Coatings ???
Im restoring my 1969 and considering going a different route with the frame. Being in the construction business I have an opportunity to use one of my suppliers to help with my frame. He does Hot Dipped Galvanizing for me with hand rails and other exterior metals we use. He can dip my frame is a solution to remove all rust, this he called "pickling" and then dip it in hot galvanizing material. He said he will only add 5 mills of thickness and wont affect any dimensions or clearances. After that is complete I am going to have it primed and sprayed with a black satin finish high quality paint. To look at you would never know it was galvanized after it was complete. I realize this is not "correct" but it sure would get all the rust out and would never rust again. Im looking for opinions and thoughts on this...Thanks.

I didnt consider the heat issue. But I did talk to a painter that said to use a primer that goes over galvanizing and then paint it however you want to. The galvanizer said he has done car frames in the past. i dont know the results though. I was more worried about the dip to remove the rust. What if he pulls it back out and its swiss cheese!!!!

I can get it done for 200 because I gave this guy al;ot of business over the years. Its just a minimal charge. Im sure it would be alot more just going to someone cold. Kinda hate to pass it up at that price.

my dad used a por15 on his frame and suspension parts. turned out great and it seems to have permently adhered to all well. after studying your post more clearly i realized that this was the answer you were not looking for. but your oppurtunity sounds good.

I worked in the steel industry for many years. Although I was in information systems, I worked closely with the sales department. What I picked up is that hot dipped galvanized steel has what is called spangle. That is the finish that the old metal garbage cans had. Paint did not stick to it very well at all. It wasn't until the electrogalvanize process was perfected that auto manufacturers started to use galvanized steel. Even then the steel had to be prepared properly for the paint to stick. Unfortunately, I don't know what proper preparation entails and I don't know is something like POR-15 or powder coating would stick to hot dipped galvanize either.

I talked to a commercial painting contractor that also does work for me and he said the primer you use after you galvanize is critical. The primer makes the adhesion to the galvanizing and then you can use any paint since it will stick to the new primer quite well. I didnt ask him about the por15, but not sure if I need it with such a good base. i was thinking of going with a commercial black paint acrylic enamel.

Don't know if this is worth anything to you but, when we put up anything that is galvanized like chimney caps, and the customer wants it painted we wash it down with vinegar and paint it. I have checked on some that we have done and after 3 years in the hot sun the paint has adhered with no problems.

I expect to get my frame back from the galvanizer this week or maybe early next week. I hope he doesnt hand me back a "Galvanized Pretzel". I have dealt with this company on alot of galvanizing through my job so he is the best around this area. The owner is who Im dealing with. His V.P. of operations came out and looked at the frame before he would do the work and he said theres no problem with galvanizing it. He also said on a "delicate" job like this one, his shop foreman and two of the shop guys would have a meeting prior to doing the work to see how to best handle it. All sounds good to me so far. Ill definately get pictures when I get it back. I have a painter that is going to look at it and recommend what primer to use before painting. There is an "etching" primer that will "bite" into the galvanizing. Ill keep you posted...

Galv. frame
I would not do it Galvo. doe's not like paint over it usualy flakes off, If you want something permanant go with sandblasting then a powdercoat you will not be sorry.. It is Beautiful when finished and nothing will harm it..
