This is the part that is the most time consuming and critical to achieving a very good finish product. Preparation of the parts/pieces to be painted.
Time and budget will always dictate what you are going to do and achieve. I had no idea when I started my 1200 engine rebuild and paint project how much time I would need, even though I realized that family requirements and just plain living would play a part in the timeline.
Budget is something that you deal with and make a decision on what to do when it comes to this. Either the issue becomes part of the project or it does not.
Time on the other hand is a nebulous concept that is hard to quantify. What is your time worth? I can say that this has been the issue many times throughout my paint projects especially during the parts/piece’s preparation phase. There is no doubt that we are all capable of doing the work, but there are a few considerations.
Do you have the equipment? I have read quite a few restoration threads and I’m jealous of those that have a lathe, welding equipment, media blasting equipment, and other really neat, nice to have equipment.
I have the pleasure of being able to use our double car garage as my workspace. The only requirement is that the Mrs’s car be in the garage overnight, small price to pay for this luxury.
Bought a media blasting unit, but the setup, and cleanup was time consuming and messy, and with a project such as mine, setup and cleanups have to be extremely beneficial – time is money so to speak.
What did I spend the majority of my time doing, sanding, ABS crack repair, priming, figuring out how to do the job. Once the parts/pieces were ready for paint application, building/making jigs to make the paint process easier.
I built a small paint booth with a fan attached. Kept the overspray down to a tolerable level. I put together a lazy Susan so that I could turn the parts/pieces and minimize handling during the paint process. Use this lazy Susan for the engine rebuild as well, supports the full weight of the engine.
To do a good job I recommend taking every part/piece apart. Remove all chrome, emblems, lights and anything that is attached to the parts/pieces to be painted. Ziploc bags are your friend to keep everything orderly and to make the install of these after all is done easier.
Before proceeding, wash and clean every part using DAWN dish soap. May take a few tries to get all the crud off each part/piece but this is extremely necessary. Don’t shortchange yourself at this juncture, you will notice it later on if you do – may look good but a little grease/oil will be problematic later on.
Once you have everything taken apart, wash and clean again.
Be careful taking off faux chrome strips as these are generally not available and the size of some of this faux chrome is different from what you an get today.
Take note of all areas to be repaired from crack to missing plastic. ABS panels are easy to work with and repair, just takes time. Generally, have to build up the area over a few days.
Hairline cracks in the original finish have to be removed. Remove the material around the crack sown to the base material, seal and build up to where you started the repair process. A fine body filler can be used to expedite this process. If you do not do this, you risk having these cracks visible in the new paint finish.
If you are working on a paint finish that is in good shape and still well adhered, don’t remove this – not necessary. Feather the edges with sand paper, preferably wet/dry. Prime the entire part/piece to prepare for paint application.
This is a good time to install ABS pieces to strengthen various areas such as where racks are attached to lids.
If the part/piece to be painted is in good condition overall and does not require any repair(s), the red/grey scrubbies you get from your local paint store are good for scuffing the OEM finish so new paint will adhere.
If you are more comfortable using wet/dry sand paper, start with a 600 grit (use wet), and then finish with 800 grit (use wet).
Once you get to this point, have all repairs done, initial sanding done, and parts/pieces primed, take some time to look at your schedule and make sure you have not missed anything.
Some of the parts/pieces of your project may be in terrible condition. Exhaust headers, centre stands, swing arms, anything that is open to road crud may be, no probably is, in rough condition. You have a decision to make and take with these parts/pieces. Do you take on the cleaning and restoration of these, or do you send them out to be done?
My paint project blossomed as time went on. This was mostly because of parts availability, and couldn’t go anywhere anyhow. I had to decide what my time was worth, could I be doing something else that only I would be doing because of what it was.
I had an estimate of what it would cost to have media blasting done by a shop. Having 5 or 6 pieces media blasted, ready for primer and paint application, and spending say $100.00 CDN for this service while I am progressing the work required was in my mind a good use of my time and money. I do know that the more part/pieces taken in at one time further reduces the cost per item. It’s a cost benefit issue, and has to be worth it to you.
Media blasting of parts/pieces is one of the few ways to get a good surface finish that will look good once the final coat(s) of paint are applied. It is sometimes the only way to get through the accumulated rust and crud that has built up over the years.
If you are going to prime and paint, standard media blasting is the order of the day. If you want to keep the OEM look without removing a lot of surface material, vapour blasting is an option.
Vapour blasting is a water-based media blast that removes surface crud and leaves the surface finish quite smooth. If your intention is to paint the part/piece after media blasting, do not have the part/piece vapour blasted.
When you paint a part/piece, or have it powder coated, the finished product is generally crud/crap resistance for a while depending on how you use your bike. When you vapour blast a part/piece, the surface area is unprotected. There are not a lot of products available to protect a vapour blasted surface.
When I had the engine parts and pieces vapour blasted, the fellow doing the work recommended ACF50, a good product but it is a fluid and as such, would collect all sorts of crud/crap over time. I wanted a protectorant that would hopefully reduce this probability, and aid in cleaning the various parts/pieces after the bike is back on the road.
I researched this requirement and found a product produced by CERAKOTE; a gloss clear coat specifically formulated to protect all sorts of aluminum finishes including a vapour blasted surface. The product is MC-5100. Contacted the company regarding this product and the company mentioned that it can be used on a vapour blasted finish. The company also mentioned that most of its MC clears would work as well.
This product is a one stage application, put in a paint spray gun with no reducer and apply. Only need one coat. It is also good for protecting painted surfaces. My hope is that this product will stand up to the rigours of the motorcycle world. Time will tell.
The preparation phase is the most critical aspect to achieving a good factory like finish.
In good weather I spent say two hours painting the motorcycle parts/pieces. This was for one or ten pieces setup to get to painting generally took me two days. I would spend 3 weeks prepping the parts pieces for these two hours, sometimes longer depending on what had to be done. Read any thread on painting and you will find this mentioned as being the most critical part of the paint project.
During this phase of the paint project, you may very well get discouraged because of the time it is taking. I went through this mindset many times and still having these thoughts. Unless you want the project to become a backyard lawn ornament, don’t lose heart. My friends here mention that I love doing this type of work. I keep correcting them mentioning that it is the end result I live and do this for.
