After a thorough wash in hot soapy water I shot 5 or 6 coats of regular halfords clear coat leaving around 15 minutes between applications. I found the key to getting a good gloss finish is to apply the clear coat in light layers holding the can around 3 to 4 inches from the chassis, any further away I find that you get more of an 'orange peel' which needs to be flatted back then polished to give a glossy result. You need to make sure you get an even covering I found it helps to have a light above where your working to check the covering.
Actually, if it's for a shelfer, there's no need to go through all that clear-coating and subsequent wet-sanding to get a glossy look. Once you've finished wet-sanding up to 1500 or higher grit, the key to getting a polished finish is simply applying rubbing compound and giving it a good buffing, then do the same with polishing compound. I usually follow that up with an application of Nu-Finish Scratch Doctor. There's no need for a clear-coat protection for a shelfer, IMHO.

In fact, it's not the clear-coat that makes the finish glossy, but the wet-sanding you did (all over again) after the 1500-grit. If you're spraying clear-coat out of a rattle-can, I almost guarantee you'll get orange-peel, regardless of methods. That will just have to be wet-sanded out again. For a shelfer, just skip the clear-coating and apply rubbing compound, polishing compound, and Nu-Finish Scratch Doctor after your final 1500-grit wet-sanded surface.

Just saying this to warn others in advance before they start clear-coating everything and getting frustrated with having to waste more hours wet-sanding out the orange-peel you just put all over your nicely sanded surfaces. ;)
Perhaps I was lucky but I didn't get orange peel, although to fair I have got it the past when I've painted bits and pieces on my road cars.

I don't disagree with want your saying but I used the clear coat to minimise the amount I had to sand away, a bit like using the clear coat as a filler in certain areas.

Cheers Alex, I suspect that there are too many deep scratches in my chassis for it to work :(

By the way, you can use some good metal polish and get a chrome like finish on that motor plate, or as I have done in the past, you can respray it silver. For one of my JRX2's I found a semi-flat silver that looks very close to the original finish.
It's just rattle can car clear coat, I'm not sure how hard wearing it would be for a runner. I thought about painting the motor mount but I wanted to keep the losi stamp visible on the rear and I wanted to keep a matt(ish) finish hence why no polishing.

I was the only one who ran a Yokomo at Oakdale back in the day, most others ran the procat.

It was at Pontllanfriath leisure centre back in the late 80's. Raced for around 2 years. Gave up when I discovered mountain biking. From recollection I believe the club moved to Markham in later years.

I didn't have to bring any work home this weekend so I thought I would spend the time doing a few jobs on the Losi.

I finished the chassis a while back so I left the clear coat to harden for a couple of weeks.

I concentrated on getting few jobs completed on the front end.

Shock mount, front arms and bulkhead complete, I used some trinity shock mounts to add a bit of blue bling and a white bulkhead, I'm not sure is the right one but I think it looks good.

Mounted to the chassis

Image

Added the rebuilt shocks

Image

A good second hand bumper mounted

Image

Lastly, cleaned up original steering mounted.

I'll complete the rear end and suspension when I receive the titanium turnbuckles from Hong Kong in a couple of weeks

Whilst this thread is from looooooong ago I have a feeling that that JRX Pro was about 90% made from one I sold years ago.

But when I sold it it was a Pro SE and didn't have a box, but it definitely had a Fibre-Lyte chassis and the moulded pink wing with Fibre-Lyte stickers on it, so I'm 99% certain that was my old Pro SE!
I regretted selling it soon after -- I didn't know that it was still (just about) possible to get parts to keep it running, and I'd become nostalgic for it almost immediately afterwards... :(
Also had no idea at the time that there would be such a surge in the popularity of vintage racing!

(It being a Pro SE explains why it had the swept front arms and slipper, which weren't on the JRX Pro I don't think?)
