Hey all, just wondering if I could get some advice with fixing up an old Speedwell frame for my better half.
The paint on the bike is actually is real good condition for it's age (40 years) with a few expected chips here and there. I'd actually like to keep it how it is but wanted to put some sort of protective layer over the top if possible so was thinking of clear coating it which will give it a little bit of a glossy finish too.
My question is: Do I need to apply a layer of another solution before clear coating? Some sort of solution which will allow the clear coat to stick the paint?

^ I'd just give it a good clean with some metho or similar then apply the clear coat. Use gloves to avoid fingerprints. Keep in mind clear coats are still porous, so while it will help keep the paint in good condition, it won't stop rust from forming.

Sounds like a good idea to me. Luckily, there is actually no rust on the frame, just a little on some components which I'm working on so not too worried about rust forming on the frame.P!N20 wrote:^ I'd just give it a good clean with some metho or similar then apply the clear coat.

Clear coat doesn't seal the surface completely and further oxidation could occur. Use a car paint cleaner initially. For the stubborn stuff try meths. Seal with ph neutral wax or similar.
One of the golden rules of conservation is "do no damage". You can always remove the wax with meths. The clear coat is harder to undo. The wax is likely to be cheaper than the clear coat so win-win

Thanks mate. By car paint cleaner, what do you mean exactly? Like a general car wash solution or a car polish type solution?RobertFrith wrote:Clear coat doesn't seal the surface completely and further oxidation could occur. Use a car paint cleaner initially.

Yep, car wash. Household detergent is reputed to have unhelpful stuff in it, I wouldn't know though. Degreaser should be used with caution too, it can damaged decals.

I actually use Penetrol with great result.
My steel frame do have some surface rust. So it helps to draw out moisture.
For your application, Penetrol prep. surface, either metal or enamel painted, will make the clear coat sticks a bit better. I have tried with or without, there is a different.
Only thing is make sure Penetrol is completely dried before you applied the clear coat.
