degreaseing for paint

[RobertThoreson]

I'm sure this has been covered but the search is not very friendly to me. Just wondering how to degrease my motor so I can repaint it. It's a 58 fastwin and it looks good but there are a few places the paint is chipped and the only way ik how to do this involves tearing it apart and parts washer it, witch is not going to happen

Back in the day we use to use Palmolive dish soap and water to degrease the cars before painting .Worked just ducky.

Back in the day, may dad used CRC degreaser in his auto body shop before painting. It came in gallon cans.

Today, there are many different CRC aerosol cans. Not sure which one is the equivalent.

Gunk engine cleaner, followed by dawn dish soap.

Wax and grease remover works to

I too have been rather impressed by purple power. That stuff is pretty strong when used full strength. I find I can water it down some and it's still effective. It seems to work quicker than simple green for me.

Will it really be ready for primer then?

The look of the final paint depends on the preparation that went into it so if you want a 'New Motor' look, you'll have to fill and sand all of the dents and scratches in the old paint. Get ready to work evenings and maybe a weekend or two to achieve that perfect base for the new paint. The same goes for a matching tank. If you primer and paint over the existing paint, any flaw will show through. If the old paint isn't perfectly grease free before priming, there's a good chance the new paint will peal off. Scuffing the paint first in the tight spots with a steel wool type of pad will help.

MEK is good stuff, much stronger than acetone. But you might lose some paint.

Simple green is corrosive on aluminum so wash well afterward.

A hot water pressure washer would be good is you could find one.

I do like it a lot,but sometimes it irritates my hands if I am using it for a long time while scrubbing something. I suggest avoiding contact with it for long periods.

Thanks for all the tips guys. I'm a detailer by trade and there's a body shop right next door. I plan on painting the actual motor and after I wash it, how meticulously do I have to rough up all the little nooks and crannys?

A successful and nice looking paint job is probably 90 percent prep.The better you do on the sanding etc the better your paint job will be and the more satisfied you will be.

Do a simple clean to remove any oil and grease and then fair out all the nicks and chipped paint areas before doing anything else. And if the chipped paint reveals bare metal, you have to primer those areas first. And if that bare metal is aluminum, you should use either a Zinc Chromate primer or an etching primer first. Then follow that with a sandable primer. And after getting everything primed, look over the entire engine and sand if there are any suspect areas. Then paint. It really depends on how nice YOU want the final finish. If you want new finish, it takes a lot of prep. If you simply want the chipped area covered, then do some spot painting and happy boating. There are no shortcuts to a glossy showroom finish. JMHO

I don't need showroom but I want to be able to take pride in it. My boat is also a 58 and I want to be able to drive it threw the marina amongst the yachts and not have to feel like I don't belong

I can understand that. If you want to see my process, click on the engine rebuild link below and have a look see. Yes it is totally tore down and rebuilt. But you can also see the painting efforts I used and do a modified painting effort yourself from those pictures. I realize it will look a lot more complicated then it really is because of the total rebuild. But it really isn't that difficult to do something a little less involved and make it look great.

Automotive base/clear paints were used and applied with a gun. All parts were bead blasted before doing any bodywork.
