Hi, I was wondering if I could get some opinions on the project I am tackling at the moment. I have a 1970 GS hood that I am planning on putting on my 1971 Skylark. The GS hood has a couple of spots of surface rust (some medium size - three inches - and some tiny). I bought the POR-15 chemical stripper and started to remove the old paint and primer (getting quite high in the process). I'm going strip all the paint off and then remove the surface rust with steel wool and light sand paper. My question is should I paint the spots where the surface rust is with POR-15? I was thinking about perhaps giving the hood an entire coat of POR-15 (I would have to brush it on as I do not have a spray gun and never used one before) before taking it to the bodyshop to have it painted for the car - is this a mistake? Should I just strip off all the paint and let the bodyshop prime and paint the hood and skip the POR-15? Any advice anyone could give me would be most appreciated.
I have to respect POR for it's masterful marketing. Chris, POR is an "ok" product if you want to save some time and "Paint Over Rust" (which is what POR stands for). If you want to cover up some rust on your floor or something like that, its "ok". But PLEASE don't put in on outer panels when there are proper products made by the real auto paint companies who cover the trucks, trailers, cars and buses of the world. You want to clean the rusted areas with a 3M "clean and strip" disc, or a 3M Roloc "Surface conditioning disc". Then treat it with a metal conditioner or etch primer. Then epoxy prime it. Use quality products in a SYSTEM designed by the paint company you are going to use as the top coat for best results. Brian
>>Hi Brian. Thanks for your advice - I really don't know much on how to remove rust so you have been a big help. Can I get the metal conditioner or etch primer at a local store?
You'll need to go to an auot paint supply store. The counter guys can help steer you in the right direction with products.
Painting you hood in the nude could be dangerous, you could get weird chemicals on your weiner. Ha-ha, get it? Stripping & painting your hood. Okay, that was lame.
Easiest and quickest solution is for you to remove old paint with paint stripper. Wipe entire surface with lacquer thinner or acetone to remove and stripper residue. Get some phosphoric acid and just brush it on. Let it cure and take the car to the body shop. You can get all the chemicals at Home Depot. Here is a pic of phosphoric acid. You can use it on anything on the car that has rust or may get rust.

>>Thanks for all your advice guys. I did as much as I could before taking it to my body guy - he had me take it to his sandblaster specialist and she did a gorgeous job on the rest (both top and under the hood), no warping or metal loss at all. The hood was primed with rust bullet and now is being gone over by another guy who is smoothing out any imperfections on the hood by hand. Then the car is going into the shop and the paint and striping will be done.
The hoods are the same (except for the pop-up spring and washer squirters). You just need to install the correct year-specific trim on the front edge.
>>Yeah, I bought the 70 GS hood knowing that I could use it on my 71. I have the correct 71 front lip moulding, the pop-up spring and washer nozzles. The only difference is that I decided not to use the 71 grills as they are plastic, and instead picked up a pair of very nice used 70 grills which are metal.
??? Not to steal anybodies thread....but what would be the best thing to remove the red paint from a pair of 1970 GS chrome rocker panel moldings? On my car they would look better...without the red paint. Thanks, :grin:
I have a 70 hood on my 72 Skylark also, how did you install the popup spring as there is no factory provision for it?? Dave B
