I have had mixed results dealing with Revell parts replacement service. I have received replacement parts from Revell that had the same problems as the original parts. Another time they have completely ignored my request. My most recent experience was right before Christmas last year when I bought Revell's 55 Chevy hardtop kit and found that it had a cracked windshield. If there is problem with a kit I usually return or exchange the kit. In this case it was the last one in the store so I couldn't exchange it and I really wanted this kit so I went to Revell's website to see about getting a replacement part. The website stated that in order to receive a replacement part you must mail to Revell customer service the original sales receipt, UPC code cutout from the box, photo copy of instruction sheet, with requested part circled. I mailed my request to Revell around January 1st and after 5 weeks they had not responded. Frustrated I sent another request via their online parts request service explaining to them that I have previously mailed my part request 5 weeks earlier and have not received the part. Then yesterday I opened mail box and found two little brown boxes from Revell. They sent me two windshields when I just requested one! Oh well I'll just have an extra for the parts box. If I ever need a replacement part again I am definitely requesting it online! I eventually get the part and I thank Revell for standing by their products.
