    Tank Restoring Notes

Somebody at Hitchcock's said "the stripe was a decal on the originals. If so, then don't worry about painting, just buy the decal. " Can anyone else confirm if this advice from Hitchcock's was accurate?- "Bob Cram"
Yes I can confirm that the red stripe is a decal. I got mine from Burton Bike Bits.

Hi Guys
Ross Thompson did my series one tank 5 or 6 years ago,. He will do a first rate job.

I tried the decal on my Series 2 tank and it didn't last. Gasoline spill made it wrinkle and lift. I ended up having Terry Smith of T&D Impex, the Canadian Bullet importer paint it on. That was 3 years ago and it's still perfect. If you try the decal, I'd clear - coat it to save it from a gas spill.

Also don't forget that the front mounting flange with the bolt hole is painted black.

Have Fun!

I can vouch for Ross as a tank restorer as well. He's done over a dozen tanks of many types for me over the past 10 years, and he is a master. Several of the tanks he did for me looked completely un-repairable when he started, and were perfect when he finished. A great guy, and always very busy.

Ross tends to be booked for months, but waiting is very worthwhile.

I've seen the "paint stripe decals" that are available, and they are in a word, pathetic. This said, I don;t think they were original ... if they were, maybe it was for a short period until the shortcomings became evident.

My memory is fading, but I'm sure the nearly new Series II I had back in 1970 had a painted stripe, and the stripe in my current Series 1A was most definitely original, and painted on.

Let me caution you about painting the stripe on the chrome tank. I had mine re-painted by a local friend and craftsman using urethane; a beautiful job. However, the heat of the summer sun was such that the paint started shrinking, and the edges of the paint begin to lift from the chrome and crack.

May have been not enough adhesion to the chrome, or maybe the paint and primer thickness was too great.

I have a series 1A as well and see evidence that it was painted. I recently rechromed the tank and bought the decals, though don't see how:
1) they can wrap around the front of the tank without wrinkling, and
2) they'll never stay on given exposure to gasoline.
I figure if if its going to be done properly that painting is the way to go.

What other bikes have chrome tanks with paint on them? That would give me a starting point to ask some local folks.
BSA Victors, chrome and yellow paint?.
Lots of the older BSAs had paint over chrome. I did my own search and didn't find a lot of useful info on the web. But here's what I did find.

1) The best info seemed to be in the Brit-Iron archive. If you go to their archives search engine and type in "paint over chrome" it brings up a list of good messages on the topic. Essentially, it seems to suggest that you need to tape the tank up to where you want to paint, then rough up the chrome surface of the section to be painted as best you can with something like emery cloth. Then paint. The URL for the search engine is:

http://listserv.indiana.edu/cgi-bin/wa?S1=brit-iron-l

2) This site isn't about painting over chrome, but had an interesting piece on a very tough topcoat that can be applied to chrome to protect it even further. The site is, and what follows that is the information on the product at that webpage. You'll have to scroll down to find it.

"GLISTEN PC
A Brilliant Two-Component Clear Coating

Glisten PC is a High Gloss, Rock Hard, Water-clear topcoat designed for spray or brush application over all metal surfaces, including highly polished aluminum and chrome surfaces. Glisten PC will not leave brushmarks, and will dry in less than one hour, but will take 3-4 days to reach maximum hardness.

When Glisten PC is first dry to the touch, it will appear to be very soft. Avoid touching it for several days until it becomes hard and tough. Accidental contact could damage the surface before full cure has taken place. Like many other coatings, Glisten PC is a MOISTURE-CURED coating, which means it is strengthened by exposure to moisture. It will never crack, chip, peel, or yellow, and is very flexible as well.

IDEAL USES: As a protective coating on aluminum wheels, chrome bumpers, marine railings, chrome or aluminum covers, grills, handles, ornaments, lights, etc."

3) Since SRM does a lot of BSA restoration, I checked out their site at
http://www.srm-engineering.com/_data/srmservices.htm
All I found was:
"Rechroming Petrol Tanks

Since the vast majority of BSA twin petrol tanks have paintwork applied over chrome this presents us with certain difficulties. Many tanks have suffered some sort of damage, ie dents, corrosion etc, and the finish of the chrome is often tarnished or pitted. We therefore offer a repair and rechroming service. To successfully rechrome any tank it must be totally stripped of all remaining chrome and nickel, at this stage any repairs can be carried out by our experienced panel beater. The tank is then polished to a mirror finish prior to chrome plating. Once plated the side panels are masked and the tank prepared for maximum adhesion of the paint. to follow. During the paint process one or more pinstripes can be skillfully applied around the edge of the chrome. Petrol tanks can be painted in most colours or matched to an original BSA colour. We also repaint tanks from other makes, ie Triumph, Norton, etc."

Hi, have enjoyed all the discussion on the tank restoring, mine was painted not to long ago and it looks fab.

Rick Brown who restored the bike is well respected in the pacific northwest and i can get his phone number if anyone wants it, he did the painting if anyone wants a picture send me an email ccpb@w...

cheers

Hi All
I believe that in addition to abrasive treatment, an Etching Primer is also required, but maybe that goes without saying.

A Different Tank 'Strip' That paint strip on the tank shown on the photo, never lost it's edge or surface. It was topped off with several coats of clear lacquer. Still looks the same actually. Regarding the decal glue on tank strip, scratching, sun, fuel would all eventually ruin it.

Whether it was painted on some year models and not on others remains an interesting question, which I'll add to remaining questions in the knowledge base.
It would be of interest for those who want to stay 100% original, rather than decorating with cartoons.

Cheers "Royal"

    Tank Decal

I have re-chromed my petrol tank. Next thing is to put on a transfer with the logo. But I am not sure what is the correct logo for my Mk2 1970.
There seems to be at least 2 different ones.
1. Royal Enfield in large red letters
2. Royal in red, Enfield in black on a blue background

Could anyone with a Mk2 -70 advice me please. TIA
Best regards "Anders"
There is an original series 2 running around Chicago.
It has the red letters with no background.
I could try to get you a jpeg., "Rick"
Anders,
The Series II used two different transfers on the chrome export tank..
The early models had a plain "Royal Enfield" in your choice of large letters in red, black or white
The later ones had "Royal Enfield" in a kind of futuristic script, with a swirl around it like Saturn's rings.

Tank Decals

For the Series11 Steve Wilson states it was as the '67 Road Sports except tank transfer "Royal" in red script,"Enfield" in black capitals,(This is the script pictured in the Series11 sales brochure on the website),the "RE" motif on the engine crankcase is picked out in red.

The same holds true for '70. But as we all know the block letter transfer was available on both the '69 and the'70 as well as the script style, so he is a bit inaccurate on that, in fact the only picture of a non-UK Series11 in the book has the block letter transfer on the tank.. Bob
