l do not think radweld will work its good for rad leaks.k seal is good and may do the job its full of little pieces of copper that fill the holes.there are some new ones on the market that cost 30 to 40 pounds.these are sold at motor factors and cliam to be good but l have never used them.maccess at bradford had one on the counter last month that was recomended by the store man. may be worth a phone call,but you may have to be trade to buy it. you will get the make and a supplier who retails it
