Best Clearcoat; PPG, Dupont, Other?

Just wondering what the best clearcoat is for fairings. I hear that PPG 2010 is the best, but I also hear Dupont is a contender.

I'll be painting my fairings again and like the title says, I'd just like to know what the best clearcoat is.

I've used stuff before that didn't harden the way I'd like or melted when gas touched it.

Cheers,

Asking which is the 'best' is kind of like asking which 180 tire is the best. It really depends on what you're planning on doing with it. PERSONALLY, I use PPG 2042 for high-volume stuff (dries hard enough to sand in 6 hours, shippable in 12), and 2002 for things that need high-gloss, as it's got a 'buffable' time of like 3 years or something (exaggeration.. but it's EXTREMELY easy to buff, even 2 weeks later during the summer). Doupont's 7600S is similar to PPG's 2042 (super-charged drying time). I've used it, but I HATE the way that Doupont sprays 'thick'. My guns just seem to hate Doupont's clears. However, after they are on.. they are as easy to buff and perform similar to PPG's comparable products.

If you want SUPER DOI (Distinction Of Image (how 'reflective' a clear is)), House of Kolors Clear is supposedly the top of the line. It's also the 'runny-est'. Extremely thin, I've shot it through a 1.3 tip and it looks like I"m shooting through a sealer gun. There are tons of 'low-grade' (See: Omni, Nason) clears available that will work just as well if you're not going for show-quality. HOwever, be forewarned, when the side of the 2042 can says you have 18 to 36 hours to buff, you have 15 to 40.... when the Nason can says you have 18 to 36 hours, you have 20 to 24.

Get ahold of your local paint rep, be honest about what you're looking to do and about your skill level (some clears may be more difficult to shoot) and your equipment and go with what they recommend.

Good luck and post pics!!
Phil

Thanks for the information and detailed response, Phil. It's greatly appreciated.

I currently race a TZ250, so while it's a race bike and damage is inevitable (but not often), the pitts are always filled with show quality bikes (believe it or not), so ultimately, the goal is a high quality, gloss / reflective finish. Unlike others, since I do the painting myself, I'm not financially burdened with the cost of having someone else do it, so I can definitely afford to use some of the best clears available. Until now, I've just been experimenting with different brands and thus far, the shop I buy materials from have not been of any help.

The House of Kolor sounds great, but my local shop is a PPG dealer and doesn't carry HOK, so I'm stuck and/or satisfied with the PPG clears.

So, in your opinion, based on the above, what would you recommend, the PPG 2042 or 2002?

By the way, which clear(s) did you use on the bikes showcased in the gallery of your site?

Cheers,

If you're really looking for highest DOI, HOK is the way to go. PPG and doupont both have Premium clearcoats, but the HOK is what allot of builders prefer on show-cars, because it DOES have higher DOI. Ask your supplier if you can order some in, most likely they can ship it in from their distributor. If not, you can check with online suppliers to send you some UFC19 (High Gloss, Low 1.9VOC for Cali squirters) or some UFC35 (Super-High Gloss, 3.5VOC if I remember right..similar to the famous UFC1).

Most of my repair jobs get PPG2042 because of the time factor. I can do bodywork, repairs, and spray my sealer one day. The next morning I can shoot my base, then clear it. By the afternoon of the 2nd day, it's ready for polishing, shippable the morning of the 3rd day.

The super-shiny clearcoat jobs you are seeing on the paddock probably are just regular, 'normal' clears (as opposed to the high-priced, Premium clears). PPG2002, ChromaClear. What makes a clearcoat job look 'professional' is usually achieved in the colorsanding and polishing. It's POSSIBLE to have clear a peice and have it come out PERFECTLY smooth, no orange peel, no runs. But it's not easy. I've been shooting for quite a while, and I've only had one peice go out that I didn't have to sand orange peel out of (I hate runs..).

So if you're going for super-high-gloss, I'd use the PPG2002, follow the spec sheets EXACTLY, then figure out how to polish the peices. It's not something you can use an automotive polisher for... the pads are too big to get down in some areas.

The DOI is how CLEAR the clear is (the higher the DOI, the less the clear distorts whatever is under the clear. VERY low-DOI would be considered 'yellowing' clear, or 'murky'). High DOI does NOT mean the clear is more-glossy. Your gloss comes from how smooth and uniform the surface is. Most people dont really notice the DOI (until you do artwork then clear it with a low-DOI clear...), but they notice all of the reflections in the surface and they 'rate' the clear by how smoothe it is. You can make the cheapest no-name clearcoat flat and smooth if you use the proper polishing techniques.

Hopefully that answered your question.

Oh.. and just to show you the difference between 2042 and 2002...



This was 2002:



This was 2042:



Both pictures are still in the booth, no polishing... just raw clear. VERY difficult to tell the difference. After polishing, they still looked nearly identical. Just the 2042, I was only able to polish for about a day, the 2002, I could have polished weeks later.

You're a good dude, Phil. Thanks for the note-worthy responses.

I think I will go with the 2002, but could you tell me what catagory the PPG 2010 falls into? That's what the shop was recommending for me.

Cheers,

2010 is a "Premium, Speed-Clear". It's not quite as quick of a clear as 2042, but has less VOC's and is easier to polish.

Here are the P-sheets on the two:
DCU-2042
DCU-2010


Those will give you a good understanding of how similar the two are, and how to use each one. 2042 is really setup to be baked and polished immediately (like... spray the clear, bake it at 140 degrees for 15 mins, then polish immediately.

If I remember right, I've used 2010 before, but my local distributor doesn't stock it in anything but gallon containers. I use the speed-clears on repair jobs, which I dont need a gallon of most of the time. I'd think that 2010 would work as well for you as 2042 for air-dry applications. At least, that's what the P-sheet says.


Best of Luck
Phil
